Abstract
This systematic review and intervention content analysis used behavioural science frameworks to characterise content and function of interventions targeting supermarket shoppers' purchasing behaviour, and explore if coherence between content and function was linked to intervention effectiveness. Study eligibility: in-store interventions (physical supermarkets) with control conditions, targeting objectively measured food and/or non-alcoholic drink purchases, published in English (no date restrictions). Eleven electronic databases were searched; reference lists of systematic reviews were hand-searched. Methodological quality was assessed using the GATE checklist. A content analysis was performed to characterise intervention content and function, and theoretical coherence between these, using the Behaviour Change Wheel, Behaviour Change Techniques Taxonomy, and Typology of Interventions in Proximal Physical Micro-Environments (TIPPME). Forty-six articles (49 interventions) met inclusion criteria; 26 articles (32 interventions) were included in the content analysis. Twenty behaviour change techniques (BCTs), and four TIPPME intervention types were identified; three BCTs ('Prompts/cues', 'Material incentive', and 'Material reward') were more common in effective interventions. Nineteen interventions solely employed theoretically appropriate BCTs. Theoretical coherence between BCTs and intervention functions was more common in effective interventions. Effective interventions included price promotions and/or in-store merchandising. Future research should explore the effect of specific BCTs using factorial study designs. PROSPERO Registration: CRD42017071065.

Abstract
AIMS To use national surveillance data in Canada to describe gender differences in the pattern of farm fatalities and severe injuries (those requiring hospitalisation). METHODS Data from the Canadian Agricultural Injury Surveillance Program (CAISP) included farm work related fatalities from 1990 to 1996 for all Canadian provinces and abstracted information from hospital discharge records from eight provinces for the five fiscal years of 1990 to 1994. Gender differences in fatalities and injuries were examined by comparison of proportions and stratified by sex, injury class (machinery, non-machinery), and age group. RESULTS Over the six year period of 1990 to 1996 there were approximately 11 times as many agriculture related fatalities for males compared to females (655 and 61, respectively). The most common machinery mechanisms of fatal injuries were roll-over (32%) for males and run-over (45%) for females. Agricultural machinery injuries requiring hospitalisation showed similar patterns, with proportionally more males over age 60 injured. The male:female ratio for non-machinery hospitalisations averaged 3:1. A greater percentage of males were struck by or caught against an object, whereas for females, animal related injuries predominated. CONCLUSIONS Gender is an important factor to consider in the interpretation of fatal and non-fatal farm injuries. A greater number of males were injured, regardless of how the occurrence of injury was categorised, particularly when farm machinery was involved. As women increasingly participate in all aspects of agricultural production, there is a need to collect, interpret, and disseminate information on agricultural injury that is relevant for both sexes.

Abstract
AIM To improve the accuracy and completeness of reporting of studies of diagnostic accuracy in order to allow readers to assess the potential for bias in a study and to evaluate the general isability of its results. METHODS The standards for reporting of diagnostic accuracy (STARD) steering committee searched the literature to identify publications on the appropriate conduct and reporting of diagnostic studies and extracted potential items into an extensive list. Researchers, editors, and members of professional organisations shortened this list during a 2 day consensus meeting with the goal of developing a checklist and a generic flow diagram for studies of diagnostic accuracy. RESULTS The search for published guidelines about diagnostic research yielded 33 previously published checklists, from which we extracted a list of 75 potential items. At the consensus meeting, participants shortened the list to a 25-item checklist, by using evidence whenever available. A prototype of a flow diagram provides information about the method of recruitment of patients, the order of test execution and the numbers of patients undergoing the test under evaluation, the reference standard, or both. CONCLUSIONS Evaluation of research depends on complete and accurate reporting. If medical journals adopt the checklist and the flow diagram, the quality of reporting of studies of diagnostic accuracy should improve to the advantage of clinicians, researchers, reviewers, journals, and the public.

Abstract
The objective of the 'Standards for Reporting of Diagnostic Accuracy' (STARD) initiative is to improve the reporting of studies of diagnostic accuracy, so as to allow readers to assess the potential for bias in a study and to evaluate the generalibility of its results. The group searched the literature to identify publications on the appropriate conduct and reporting of diagnostic studies. This was used to draw up a list of potential items. During a consensus meeting, a group of researchers, medical journal editors, and members of professional organisations reduced this list to a usable checklist. Wherever possible, evidence from the literature was used to justify the decisions made. The search for published guidelines about diagnostic research yielded 33 previously published checklists, from which a list of 75 potential items was extracted. At the consensus meeting, participants shortened the list to a 25-item checklist. A generic flow diagram was drawn up to provide guidance on the method for including patients, the order in which tests were to be conducted and the number of patients to undergo the test being evaluated, the reference standard, or both. A scientific publication can only be assessed when the reporting is both correct and complete. Use of the checklist and flow diagram will improve the quality of reports produced, to the advantage of clinicians, researchers, reviewers, journal editors and other interested parties.

Abstract
Numerous examples of irresponsible authorship are associated with the rise in the number of authors per article and with the documented rise in authorship disputes. Multiple co-investigators have become the norm, and a result is that old concepts of authorship-which, when there was but one author, automatically linked credit with accountability-have eroded. The answer, in the tradition of scientific transparency, is for authors to decide together their individual contributions and disclose these to their readers. This disclosure is now required by many major general medical journals and has been adopted by the International Committee of Medical Journal Editors as the standard.

Abstract
It has recently been suggested that lycra garments are helpful for children with cerebral palsy (CP). Twelve children, with athetosis, ataxia, and spasticity, were fitted with lycra garments (Kendall-Camp UK Ltd). Scores on the Paediatric Evaluation of Disability Inventory (PEDI) scales were determined before and after wearing the garment for at least 6 hours a day for 6 weeks. Five children with motor problems representative of the whole group were investigated during a reach-and-grasp task by kinematic motion analysis; reflective markers were used with and without the garment. Carers were given a questionnaire concerning the practicalities of using the garments. All 12 children made improvements in at least one of the functional scales of the PEDI, and scores for the whole group showed significant gains (Wilcoxon chi2 test, self-help p<0.01; mobility p<0.5; social p<0.1). These changes were usually slight, although noticed by carers. Six children made gains of at least one scale of the caregiver assistance scores, two of the children showed losses (due to difficulties removing the garment for toileting), and four showed no change. Motion analysis indicated that (1) two children with athetosis had improved proximal stability in sitting and in smoothness of arm movements, (2) one child with ataxia had improved in proximal and distal stability, and (3) two children with spasticity had more jerky movements, although one improved in proximal stability. All children had problems in wearing the garments, including problems with toileting and incontinence of urine; the parents of only one child wanted to continue using it. Results suggest that the functional benefit of lycra garments for children with CP is mainly due to improvements in proximal stability but this should be weighed against the inconvenience and loss of independence.

Abstract
BACKGROUND: The Quality of Reporting of Meta-analyses (QUOROM) conference was convened to address standards for improving the quality of reporting of meta-analyses of clinical randomised controlled trials (RCTs). METHODS: The QUOROM group consisted of 30 clinical epidemiologists, clinicians, statisticians, editors, and researchers. In conference, the group was asked to identify items they thought should be included in a checklist of standards. Whenever possible, checklist items were guided by research evidence suggesting that failure to adhere to the item proposed could lead to biased results. A modified Delphi technique was used in assessing candidate items. FINDINGS: The conference resulted in the QUOROM statement, a checklist, and a flow diagram. The checklist describes our preferred way to present the abstract, introduction, methods, results, and discussion sections of a report of a meta-analysis. It is organised into 21 headings and subheadings regarding searches, selection, validity assessment, data abstraction, study characteristics, and quantitative data synthesis, and in the results with <<trial flow>>, study characteristics, and quantitative data synthesis; research documentation was identified for eight of the 18 items. The flow diagram provides information about both the numbers of RCTs identified, included, and excluded and the reasons for exclusion of trials. INTERPRETATION: We hope this report will generate further thought about ways to improve the quality of reports of meta-analyses of RCTs and that interested readers, reviewers, researchers, and editors will use the QUOROM statement and generate ideas for its improvement.

Abstract
CONTEXT Despite federal regulations on faculty conflicts of interest in federally funded research, academic-industry ties are common, and evidence exists that financial considerations bias the research record. Public scrutiny of these ties is increasing, especially in cases where researchers have financial interests in the corporate sponsors of their clinical research. OBJECTIVE To review policies on conflict of interest at major biomedical research institutions in the United States. DESIGN Cross-sectional survey and content analysis study conducted from August 1998 to February 2000. SETTING AND PARTICIPANTS The 100 US institutions with the most funding from the National Institutes of Health in 1998 were initially sampled; policies from 89 institutions were available and included in the analysis. MAIN OUTCOME MEASURES Process for disclosure, review, and management of conflicts of interest and specified management strategies or limitations, according to the institutions' faculty/staff conflict of interest policies. RESULTS Content of the conflict of interest policies varied widely across institutions. Fifty-five percent of policies (n = 49) required disclosures from all faculty while 45% (n = 40) required them only from principal investigators or those conducting research. Nineteen percent of policies (n = 17) specified limits on faculty financial interests in corporate sponsors of research, 12% (n = 11) specified limits on permissible delays in publication, and 4% (n = 4) prohibited student involvement in work sponsored by a company in which the faculty mentor had a financial interest. CONCLUSIONS Most policies on conflict of interest in our sample of major research institutions in the United States lack specificity about the kinds of relationships with industry that are permitted or prohibited. Wide variation in management of conflicts of interest among institutions may cause unnecessary confusion among potential industrial partners or competition among universities for corporate sponsorship that could erode academic standards. It is in the long-term interest of institutions to develop widely agreed-on, clear, specific, and credible policies on conflicts of interest. JAMA. 2000;284:2203-2208.

Abstract
The prevalence of asthma remains difficult to determine with precision with no absolute or "gold" standard for diagnosis. A recently developed video questionnaire for epidemiological studies with less reliance on understanding written questions provides another tool for determining prevalence and severity of asthma. This report from the International Study of Asthma and Allergies in Childhood (ISAAC) examines the agreement between the ISAAC video questionnaires on respiratory symptoms and reported asthma. Between December 1993 and April 1995, 4952 children aged 13-14 years in two Canadian communities completed sequentially the ISAAC written and video questionnaires at school. The agreement between responses to the two questionnaires for reported wheeze ever, current wheeze, wheeze on exercise, and nocturnal wheeze (the latter three questions relating to symptoms in the last 12 months), and to any combination of the latter three questions was examined in the full sample and in those reporting diagnosed asthma, using concordance and kappa coefficients as measures of agreement. The prevalences of wheeze ever, current wheeze, wheeze on exercise, and nocturnal wheeze were significantly lower based on responses to the video questionnaire compared with the written questionnaire in both regions in the full sample and in those labeled as having asthma. Although concordance between video and written questionnaires always exceeded 60% and often exceeded 70% for related questions, agreement measured by the kappa statistic for each question was only fair to moderate (kappa = 0.22-0.51). We conclude that the video questionnaire yields lower reported prevalence rates for asthma symptoms, and that there is limited agreement between responses to the two questionnaires that is not explained by issues of language, culture, or literacy.

Abstract
OBJECTIVE Because of the pressure for timely, informed decisions in public health and clinical practice and the explosion of information in the scientific literature, research results must be synthesized. Meta-analyses are increasingly used to address this problem, and they often evaluate observational studies. A workshop was held in Atlanta, Ga, in April 1997, to examine the reporting of meta-analyses of observational studies and to make recommendations to aid authors, reviewers, editors, and readers. PARTICIPANTS Twenty-seven participants were selected by a steering committee, based on expertise in clinical practice, trials, statistics, epidemiology, social sciences, and biomedical editing. Deliberations of the workshop were open to other interested scientists. Funding for this activity was provided by the Centers for Disease Control and Prevention. EVIDENCE We conducted a systematic review of the published literature on the conduct and reporting of meta-analyses in observational studies using MEDLINE, Educational Research Information Center (ERIC), PsycLIT, and the Current Index to Statistics. We also examined reference lists of the 32 studies retrieved and contacted experts in the field. Participants were assigned to small-group discussions on the subjects of bias, searching and abstracting, heterogeneity, study categorization, and statistical methods. CONSENSUS PROCESS From the material presented at the workshop, the authors developed a checklist summarizing recommendations for reporting meta-analyses of observational studies. The checklist and supporting evidence were circulated to all conference attendees and additional experts. All suggestions for revisions were addressed. CONCLUSIONS The proposed checklist contains specifications for reporting of meta-analyses of observational studies in epidemiology, including background, search strategy, methods, results, discussion, and conclusion. Use of the checklist should improve the usefulness of meta-analyses for authors, reviewers, editors, readers, and decision makers. An evaluation plan is suggested and research areas are explored.

Abstract
BACKGROUND The Quality of Reporting of Meta-analyses (QUOROM) Conference was convened to address standards for improving the quality of reporting of meta-analyses of clinical randomised controlled trials (RCTs). METHODS The QUOROM group consists of 30 clinical epidemiologists, clinicians, statisticians, editors, and researchers. In conference, the group was asked to identify items they thought should be included in a checklist of standards. Whenever possible, checklist items were guided by research evidence suggesting that failure to adhere to the item proposed could lead to biased results. A modified Delphi technique was used in assessing candidate items. RESULTS The conference resulted in the QUOROM statement, a checklist, and a flow diagram. The checklist describes our preferred way to present the abstract, introduction, methods, results, and discussion sections of a report of a meta-analysis. it is organized into 21 headings and subheadings regarding searches, selection, validity assessment, data abstraction, study characteristics, and quantitative data synthesis, and in the results with 'trial flow', study characteristics, and quantitative data synthesis; research documentation was identified for eight of the 18 items. The flow diagram provides information about both the numbers of RCTs identified, included, and excluded and the reasons for exclusion of trials. INTERPRETATION We hope this report will generate further thought about ways to improve the quality of reports of meta-analyses of RCTs and that interested readers, reviewers, researchers, and editors will use the QUOROM statement and generate ideas for its improvement.

Abstract
Herbert Hultgren, a cardiologist who kept a careful diary all his career, arrived in Peru at the beginning of 1959 to study the occurrence of pulmonary hypertension in children at high altitude with patent ductus arteriosus. There, he was told about a strange condition, high altitude pulmonary edema (HAPE), and found that to Peruvian physicians looking after mine employees and their families, its occurrence was almost routine. With his Peruvian colleagues, Herb immediately began a systematic study of the condition, including catheter studies. Though the absence of left ventricular enlargement suggested a non-cardiac form of pulmonary edema, and though this is what he suggested in his first publication, in two subsequent papers, one written with Charles Houston, who contributed cases occurring in mountaineers, Herb wrote that the most probable cause was left ventricular failure. What is extraordinary is that before he finally submitted the two papers, he had certain knowledge that in one case of HAPE at least, left atrial pressure had been shown to be normal. Herb's contributions, then and later, to the elucidation of HAPE were enormous.

Abstract
BACKGROUND Wide variations in the prevalence of asthma, rhinitis and eczema have been reported between regions within Canada and between different countries. The International Study of Asthma and Allergies in Childhood (ISAAC) was developed to provide a standardized tool and methodology to ascertain the prevalence of asthma and allergies in different regions. Comparisons of prevalence rates across geographic regions and at different times may help to identify factors that contribute to the development of these conditions in individuals. METHODS Two Canadian centres, Hamilton and Saskatoon, participated in the ISAAC. A standard questionnaire was distributed through schools and completed by 13- and 14-year-old children and by the parents of 6- and 7-year-old children. Prevalence rates and 95% confidence intervals were calculated for asthma, wheezing, rhinitis and eczema. RESULTS The overall response rates were 75.1% among the children 6 and 7 years old and 68.6% among those 13 and 14 years old. Among the younger children, the lifetime prevalence of asthma was 17.2% in Hamilton and 11.2% in Saskatoon; the corresponding rates among the older children were 19.2% and 12.2% respectively. The prevalence of wheezing in the 12 months before the survey in the younger group was 20.1% in Hamilton and 14.1% in Saskatoon; in the older group it was 30.6% and 24.0% respectively. The prevalence of rhinitis in the 12 months before the survey was 28.6% in Hamilton and 22.6% in Saskatoon in the younger group and 45.8% and 33.8% respectively in the older group. The prevalence of eczema was slightly higher in Saskatoon in both age groups. INTERPRETATION High prevalence rates of asthma, rhinitis and eczema exist among school children in Hamilton and Saskatoon, similar to rates in other Western countries. Further studies are required to determine the factors associated with the high rates in the 2 regions and possible reasons for the higher rates in Hamilton.

Abstract
BACKGROUND Authorship disputes and abuses have increased in recent years. In response to a proposal that researcher contributions be specified for readers, The Lancet began disclosing such contributions at the end of original articles. OBJECTIVE To analyze the descriptions researchers use for their contributions and to determine how the order of names on the byline corresponds to these contributions, whether persons listed on the byline fulfill a lenient version of the criteria for authorship specified by the International Committee of Medical Journal Editors (the Vancouver Group), and whether the contributions of persons listed as contributors overlap with the contributions of those who are acknowledged. DESIGN Descriptive study. MEASUREMENTS A taxonomy of researchers' contributions was developed and applied to researchers' self-reported contributions to original research articles published in The Lancet from July to December 1997. RESULTS Contributors lists occupied little page space (mean, 2.5 cm of column length). Placement on the byline did not indicate the specific category of task performed, although the first-contributor position corresponded to a significantly greater number of contributions (mean numbers of contributions: first-contributor position, 3.23; second-contributor position, 2.51; third-contributor position, 2.20; and fourth-contributor position, 2.51) (P < 0.01). Forty-four percent of contributors on the byline did not fulfill a lenient version of the Vancouver Group's criteria for authorship. Sixty percent of the most common categories of activities described on contributors lists overlapped with those on acknowledgements lists. CONCLUSIONS Publication of lists that specify contributions to research articles is feasible and seems to impart important information. The criteria for authorship outlined by the Vancouver Group do not seem to be congruent with the self-identified contributions of researchers.

Abstract
OBJECTIVES To identify editors interested in participating in a global organisation and communication network of medical editors; to assess current use of the peer-review process; and to determine current computer capabilities, needs, and interests of medical journal editors around the world. DESIGN Mail survey of senior editors at 727 medical journals. SETTING Fifty-seven countries worldwide. RESULTS Two hundred and sixty-nine editors (37%) responded. Eighty-seven per cent of responding editors expressed interest in a global organisation of medical editors. Almost all editors (94%) reported using peer-review systems. Practices varied widely across journals, but in most cases were not highly correlated with the countries' level of development: 44% reported formal orientation for reviewers; 71% used specific instructions; 39% required reviewers to disclose conflicts of interest; 36% masked the identity of authors; and 42% graded reviews for quality. Seventy-eight per cent of editors reported using a computer in their work and 47% had Internet access; two-thirds of those without access expected to have Internet access within 18 months. CONCLUSIONS There was strong interest among respondents in a global organisation for medical editors. Peer review was widely reported by medical journal editors throughout the world, although specific practices varied widely. Half of the responding editors reported having access to the Internet, making participation in a worldwide computer network of editors feasible.

Abstract
CONTEXT Authorship in biomedical publications establishes accountability, responsibility, and credit. Misappropriation of authorship undermines the integrity of the authorship system, but accurate data on its prevalence are limited. OBJECTIVES To determine the prevalence of articles with honorary authors (named authors who have not met authorship criteria) and ghost authors (individuals not named as authors but who contributed substantially to the work) in peer-reviewed medical journals and to identify journal characteristics and article types associated with such authorship misappropriation. DESIGN Mailed, self-administered, confidential survey. PARTICIPANTS A total of 809 corresponding authors (1179 surveyed, 69% response rate) of articles published in 1996 in 3 peer-reviewed, large-circulation general medical journals (Annals of Internal Medicine, JAMA, and The New England Journal of Medicine) and 3 peer-reviewed, smaller-circulation journals that publish supplements (American Journal of Cardiology, American Journal of Medicine, and American Journal of Obstetrics and Gynecology). MAIN OUTCOME MEASURES Prevalence of articles with honorary authors and ghost authors, as reported by corresponding authors. RESULTS Of the 809 articles, 492 were original research reports, 240 were reviews and articles not reporting original data, and 77 were editorials. A total of 156 articles (1 9%) had evidence of honorary authors (range, 11%-25% among journals); 93 articles (11%) had evidence of ghost authors (range, 7%-16% among journals); and 13 articles (2%) had evidence of both. The prevalence of articles with honorary authors was greater among review articles than research articles (odds ratio [OR], 1.8; 95% confidence interval [CI], 1.2-2.6) but did not differ significantly between large-circulation and smaller-circulation journals (OR, 1.4; 95% CI, 0.96-2.03). Compared with similar-type articles in large-circulation journals, articles with ghost authors in smaller-circulation journals were more likely to be reviews (OR, 4.2; 95% CI, 1.5-13.5) and less likely to be research articles (OR, 0.49; 95% CI, 0.27-0.88). CONCLUSION A substantial proportion of articles in peer-reviewed medical journals demonstrate evidence of honorary authors or ghost authors.

Abstract
CONTEXT All authors may not be equal in the eyes of reviewers. Specifically, well-known authors may receive less objective (poorer quality) reviews. One study at a single journal found a small improvement in review quality when reviewers were masked to author identity. OBJECTIVES To determine whether masking reviewers to author identity is generally associated with higher quality of review at biomedical journals, and to determine the success of routine masking techniques. DESIGN AND SETTING A randomized controlled trial performed on external reviews of manuscripts submitted to Annals of Emergency Medicine, Annals of Internal Medicine, JAMA, Obstetrics & Gynecology, and Ophthalmology. INTERVENTIONS Two peers reviewed each manuscript. In one study arm, both peer reviewers received the manuscript according to usual masking practice. In the other arm, one reviewer was randomized to receive a manuscript with author identity masked, and the other reviewer received an unmasked manuscript. MAIN OUTCOME MEASURE Review quality on a 5-point Likert scale as judged by manuscript author and editor. A difference of 0.5 or greater was considered important. RESULTS A total of 118 manuscripts were randomized, 26 to usual practice and 92 to intervention. In the intervention arm, editor quality assessment was complete for 77 (84%) of 92 manuscripts. Author quality assessment was complete on 40 (54%) of 74 manuscripts. Authors and editors perceived no significant difference in quality between masked (mean difference, 0.1; 95% confidence interval [CI], -0.2 to 0.4) and unmasked (mean difference, -0.1; 95% CI, -0.5 to 0.4) reviews. We also found no difference in the degree to which the review influenced the editorial decision (mean difference, -0.1; 95% CI,-0.3 to 0.3). Masking was often unsuccessful (overall, 68% successfully masked; 95% CI, 58%-77%), although 1 journal had significantly better masking success than others (90% successfully masked; 95% CI, 73%-98%). Manuscripts by generally known authors were less likely to be successfully masked (odds ratio, 0.3; 95% CI, 0.1-0.8). When analysis was restricted to manuscripts that were successfully masked, review quality as assessed by editors and authors still did not differ. CONCLUSIONS Masking reviewers to author identity as commonly practiced does not improve quality of reviews. Since manuscripts of well-known authors are more difficult to mask, and those manuscripts may be more likely to benefit from masking, the inability to mask reviewers to the identity of well-known authors may have contributed to the lack of effect.

Abstract
CONTEXT In a previous study, we found that masking success was higher at a journal that masked reviewers to author identity. We hypothesized that masking policy or other factors could be associated with masking success. OBJECTIVES To evaluate differences in success of masking reviewers to author identity at 7 biomedical journals and to identify factors associated with these differences. DESIGN Written questionnaire. PARTICIPANTS Reviewers at 3 journals with a long-standing policy of masking author identity (Annals of Emergency Medicine, Epidemiology, and Journal of the American Geriatrics Society) and 4 journals without a policy of masking author identity (Annals of Internal Medicine, JAMA, Obstetrics & Gynecology, and Ophthalmology). MAIN OUTCOME MEASURES Masking success (percentage of reviewers successfully masked) and reviewer characteristics associated with masking. RESULTS There was no significant difference in masking success between journals with a policy of masking (60%) and those without (58%) (P= .92). We found no association between masking success and a policy of masking when adjusted for the reviewer characteristics of age, sex, years of reviewing experience, number of articles published, number of articles reviewed, percentage of time spent in research, editorial experience, or academic rank (odds ratio [OR], 1.3; 95% confidence interval [CI], 0.64-2.8; P=.43). In multivariable analysis of reviewer characteristics, reviewers spending a greater percentage of time in research, the only significant predictor of masking success, were less likely to be successfully masked (OR, 1.01; 95% CI, 1.00-1.02) (P=.04). CONCLUSIONS Masking success appears unrelated to a journal policy of masking, but is associated with reviewers' research experience and could be affected by other characteristics. Using reviewers with less research and reviewing experience might increase masking success, but the effect on review quality is unknown.

Abstract
This summary corresponds to the translation into Spanish of the Special Communication published in the Journal of the American Medical Association in August 1996, along with the editorial published in the same issue "How to report Randomized Controlled Trials. The Consort Statement". It describes the Consolidated Standards for Preparation of Controlled Clinical Trials, prepared by a work group made up of members of the SORT Group and of the Asilomar Work Group, along with the director of a magazine and the author of the report on a clinical trial. The work was carried out by means of a Delphi process and the result was a check list and a process diagram. The check list is made up of 21 items that mainly refer to methods, results and discussions on the report of a controlled clinical trial, identifying the necessary information in order to be able to evaluate the internal and external value of the report, judging the improvement to be positive for the patient, the editors and the reviewers of the magazines.

Abstract
A published article is the primary means whereby new work is communicated, priority is established, and academic promotion is determined. Publication depends on trust and requires that authors be held to standards of honesty, completeness, and fairness in their reporting, and to accountability for their statements. The system of authorship, while appropriate for articles with only 1 author, has become inappropriate as the average number of authors of an article has increased; as the work of coauthors has become more specialized and relationships between them have become more complex; and as both credit and, even more, responsibility have become obscured and diluted. Credit and accountability cannot be assessed unless the contributions of those named as authors are disclosed to readers, so the system is flawed. We argue for a radical conceptual and systematic change, to reflect the realities of multiple authorship and to buttress accountability. We propose dropping the outmoded notion of author in favor of the more useful and realistic one of contributor. This requires disclosure to readers of the contributions made to the research and to the manuscript by the contributors, so that they can accept both credit and responsibility. In addition, certain named contributors take on the role of guarantor for the integrity of the entire work. The requirement that all participants be named as contributors will eliminate the artificial distinction between authors and acknowledgees and will enhance the integrity of publication.
