Neuropsychiatric disorders in adults with atopic dermatitis: A population-based cohort study. J Eur Acad Dermatol Venereol 2024; 38:543-548. [PMID: 37731131 DOI: 10.1111/jdv.19518] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2023] [Accepted: 09/05/2023] [Indexed: 09/22/2023]
Abstract
BACKGROUND Atopic dermatitis (AD) may be associated with an increased burden of neuropsychiatric outcomes such as anxiety and depression, but longitudinal data on the impact of AD severity is lacking, and a comprehensive assessment of neuropsychiatric disease in adults with AD is needed. OBJECTIVES Determine risk of incident neuropsychiatric disease among adults with AD by severity. METHODS A cohort study using electronic health records data from UK general practices from 1994 to 2015. Adults (≥18 years) with AD were matched on age, practice and index date to patients without AD. AD severity was categorized using treatments and dermatology referrals. Outcomes were incident anxiety, depression, bipolar disorder, schizophrenia, attention-deficit/hyperactivity disorder (ADHD), autism, obsessive-compulsive disorder (OCD), suicidality and completed suicide. RESULTS Comparing 625,083 adults with AD to 2,678,888 adults without AD, AD was associated with higher risk of anxiety [HR 1.14 (1.13-1.15)], depression [1.14 (1.13-1.15)] and OCD [1.48 (1.38-1.58)] across all severities. Mild or moderate AD was also associated with higher risk of autism, ADHD, bipolar disorder and suicidality. CONCLUSIONS Atopic dermatitis is associated with a higher risk of multiple neuropsychiatric conditions, but these risks differ by specific condition and AD severity. Clinicians should inquire about mental health in patients with AD.

Incident Asthma, Asthma Exacerbations, and Asthma-Related Hospitalizations in Patients With Atopic Dermatitis. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY. IN PRACTICE 2024; 12:421-430.e1. [PMID: 37972919 PMCID: PMC10922794 DOI: 10.1016/j.jaip.2023.11.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Revised: 10/04/2023] [Accepted: 11/06/2023] [Indexed: 11/19/2023]
Abstract
BACKGROUND Atopic dermatitis (AD) is thought to induce asthma via the "atopic march," but the effects of AD on incident asthma and asthma severity have not been fully characterized. OBJECTIVE To determine risk of asthma, asthma exacerbations, and asthma-related hospitalizations among patients fwith AD. METHODS A cohort study was conducted using electronic health records data from UK general practices from 1994 to 2015. Children (<18 years old) and adults (≥18 years) with AD were matched on age, practice, and index date to patients without AD. AD severity was categorized using treatments and dermatologist referrals. Outcomes were incident asthma among all patients and asthma exacerbation or hospitalization among patients with asthma. RESULTS On comparing 409,341 children with AD (93.2% mild, 5.5% moderate, 1.3% severe) with 1,809,029 unaffected children, those with AD were found to be associated with a 2-fold greater risk of asthma compared with those without AD (hazard ratio, 1.96; 95% CI, 1.93-1.98). On comparing 625,083 adults with AD (65.7% mild, 31.4% moderate, and 2.9% severe) with 2,678,888 unaffected adults, AD was found to be associated with a 38% higher risk of asthma (hazard ratio, 1.38; 95% CI, 1.36-1.40). Asthmatic patients with AD also had a 21% to 63% greater risk of asthma exacerbations and a 20% to 64% greater risk of asthma-related hospitalizations compared with asthmatic patients without AD. Risk of asthma, asthma exacerbation, or asthma-related hospitalization increased with AD severity in a dose-dependent manner in both the pediatric and adult cohorts. CONCLUSIONS AD, especially in children and when more severe, is associated with greater risk of asthma as well as greater risk of asthma exacerbations and hospitalizations among asthmatic patients.

Incidence of Cardiovascular Disease and Venous Thromboembolism in Patients With Atopic Dermatitis. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY. IN PRACTICE 2023; 11:3123-3132.e3. [PMID: 37572754 DOI: 10.1016/j.jaip.2023.08.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/20/2023] [Revised: 08/01/2023] [Accepted: 08/01/2023] [Indexed: 08/14/2023]
Abstract
BACKGROUND Atopic dermatitis (AD) may increase risk for atherothrombotic and cardiovascular (CV) disease. OBJECTIVE Determine CV disease and venous thromboembolism risk among patients with AD. METHODS Cohort study using electronic health data from U.K. general practices in 1994 to 2015. Children (<18 y) and adults (≥18 y) with AD were matched to patients without AD on age, same practice, and encounter date. Treatments and specialist referrals served as proxies of AD severity. Outcomes were incident myocardial infarction, cerebrovascular accident (CVA), diabetes, hypertension, dyslipidemia, deep vein thrombosis (DVT), and pulmonary embolism. Cox regression analysis was used to compare outcomes in AD versus non-AD patients. RESULTS Comparing 409,341 children with AD (93.2% mild, 5.5% moderate, and 1.3% severe) to 1,809,029 unaffected children, AD was associated with higher risk of DVT (hazard ratio [HR] 1.23; 95% confidence interval [95% CI] 1.02-1.48) and severe AD was associated with higher risk of CVA (HR 2.43; 95% CI 1.13-5.22) and diabetes (HR 1.46; 95% CI 1.06-2.01). Comparing 625,083 adults with AD (65.7% mild, 31.4% moderate, and 2.9% severe) to 2,678,888 unaffected adults, AD, especially when severe, was associated with higher risk of DVT (HR 1.14; 95% CI 1.11-1.18; and HR 1.64; 95% CI 1.49-1.82, respectively) and small but increased risks of CVA, diabetes, and dyslipidemia. Adults with severe AD had higher risk of myocardial infarction (HR 1.27; 95% CI 1.15-1.39), CVA (HR 1.21; 95% CI 1.13-1.30), diabetes (HR 1.15; 95% CI 1.09-1.22), dyslipidemia (HR 1.11; 95% CI 1.06-1.17), and pulmonary embolism (HR 1.39; 95% CI 1.21-1.60) compared with adults without AD. CONCLUSIONS Atopic dermatitis, particularly when severe, is associated with small but increased risks of CV risk factors and events and significantly increased risk of venous thromboembolism.

Abstract
BACKGROUND Atopic dermatitis (AD) is associated with immunological dysfunction, which may influence cancer development. Previous studies of AD and cancer demonstrate inconsistent results and few of these studies examined children or AD severity and treatment. OBJECTIVES To determine malignancy risk among children and adults with AD. METHODS We conducted a cohort study using electronic health records data from UK general practices in The Health Improvement Network between 1994 and 2015. Children (< 18 years old) and adults (≥ 18 years old) with AD were matched on age, practice and index date to patients without AD. AD was categorized as mild, moderate or severe using treatments and dermatology referrals as proxies. The primary outcome was any incident malignancy, including in situ malignancy, identified using diagnosis codes and categorized into haematological, skin and solid organ malignancies. Secondary outcomes included specific malignancies: leukaemia, lymphoma, melanoma, nonmelanoma skin cancer (NMSC) and common solid-organ cancers. RESULTS Among 409 431 children with AD (93.2% mild, 5.5% moderate, 1.3% severe) and 1 809 029 children without AD who had median follow-up of 5-7 years, the incidence rates of malignancy were 1.9-3.4 and 2.0 per 10 000 person-years (PY), respectively. The adjusted risk of malignancy overall did not differ with respect to AD [hazard ratio (HR) 1.02 (95% confidence interval 0.92-1.12)]. Severe AD was associated with increased lymphoma risk [HR 3.18 (1.41-7.16), excluding cutaneous T-cell lymphoma (CTCL)], and mild AD was associated with increased NMSC risk [1.55 (1.06-2.27)]. Among 625 083 adults with AD (65.7% mild, 31.4% moderate, 2.9% severe) and 2 678 888 adults without AD who had median follow-up of 5 years, incidence rates of malignancy were 97.4-125.3 per 10 000 PY and 103.7 per 10 000 PY, respectively. The adjusted risk of any malignancy did not differ with respect to AD [HR 1.00 (0.99-1.02)]. However, adults with severe AD had a twofold higher risk of non-CTCL lymphoma. AD was also associated with slightly higher skin cancer risk [HR 1.06 (1.04-1.08)] and slightly lower solid cancer risk [0.97 (0.96-0.98)] but results varied by specific cancers and AD severity. CONCLUSIONS Epidemiological evidence does not support a strong overall malignancy risk in AD but lymphoma risk may be increased with severe AD.

A framework for setting enrollment goals to ensure participant diversity in sponsored clinical trials in the United States. Contemp Clin Trials 2023; 129:107184. [PMID: 37054773 DOI: 10.1016/j.cct.2023.107184] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2022] [Revised: 04/06/2023] [Accepted: 04/10/2023] [Indexed: 04/15/2023]
Abstract
BACKGROUND Diversity in clinical trials (CTs) has potential to improve health equity and close health disparities. Underrepresentation of historically underserved groups compromises the generalizability of trial findings to the target population, hinders innovation, and contributes to low accrual. Aim of this study was to establish a transparent and reproducible process for setting trial diversity enrollment goals informed by disease epidemiology. METHOD An advisory board of epidemiologists with expertise in health disparities, equity, diversity, and social determinants of health was convened to evaluate and strengthen the initial goal-setting framework. Data sources used were the epidemiologic literature, US Census, and real-world data (RWD); limitations were considered and addressed where appropriate. Framework was intentionally designed to safeguard against the underrepresentation of groups that have been medically underserved historically. A stepwise approach was created with Y/N decisions based on empirical data. RESULTS We compared race and ethnicity distributions of six diseases from Pfizer's portfolio chosen to represent different therapeutic areas (multiple myeloma, fungal infections, Crohn's disease, Gaucher disease, COVID-19, and Lyme disease) in the RWD to the distributions in the US Census and established trial enrollment goals. Enrollment goals for potential CTs were based on RWD for multiple myeloma, Gaucher disease, and COVID-19; for fungal infections, Crohn's disease, and Lyme disease, enrollment goals were based on the Census. CONCLUSIONS We developed a transparent and reproducible framework for setting CT diversity enrollment goals. We noted limitations due to data sources to be mitigated and several ethical decisions to be considered to set equitable enrollment goals.

Abstract
OBJECTIVES Patients with atopic dermatitis (AD), also known as eczema, may be at an increased risk for malignancies compared with patients without AD; however, incidence rates (IRs) of malignancies in patients with moderate to severe AD are largely unknown. The objective of this study was to evaluate and compare IRs of malignancies in adults with moderate to severe AD (aged ≥18 years). DESIGN Retrospective cohort study using data from a Kaiser Permanente Northern California (KPNC) cohort. AD severity classification was adjudicated with medical chart review. Covariates and stratification variables included age, sex and smoking status. SETTING Data were obtained from the KPNC healthcare delivery system in northern California, USA. Cases of AD were defined by outpatient dermatologist-rendered codes and prescriptions of topical therapy or phototherapy (moderate) or systemic treatment (severe). PARTICIPANTS KPNC health plan members with moderate or severe AD (2007-2018). PRIMARY AND SECONDARY OUTCOME MEASURES Malignancy IRs and 95% CIs per 1000 person-years were calculated. RESULTS 7050 KPNC health plan members with moderate and severe AD met eligibility criteria for inclusion. IRs (95% CI) were highest for non-melanoma skin cancer (NMSC) in patients with moderate and severe AD (4.6 (95% CI 3.9 to 5.5) and 5.9 (95% CI 3.8 to 9.2), respectively) and breast cancer (2.2 (95% CI 1.6 to 3.0) and 0.5 (95% CI 0.1 to 3.9), respectively). Except for breast cancer, which was only evaluated in women, malignancies were higher (with non-overlapping CIs) in patients with moderate and moderate to severe AD in men versus women for basal cell carcinoma and NMSC and in former versus never smokers for NMSC and squamous cell carcinoma. CONCLUSIONS This study estimated IRs of malignancies in patients with moderate and severe AD and provides valuable information for dermatology clinicians and ongoing clinical trials in these populations.

Atopic dermatitis and risk of major neuropsychiatric disorders in children: A population-based cohort study. J Eur Acad Dermatol Venereol 2023; 37:114-122. [PMID: 36018560 PMCID: PMC9929490 DOI: 10.1111/jdv.18564] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2022] [Accepted: 08/18/2022] [Indexed: 12/15/2022]
Abstract
BACKGROUND Paediatric atopic dermatitis (AD) has been linked to neuropsychiatric comorbidities such as depression, anxiety and attention-deficit/hyperactivity disorder (ADHD). However, longitudinal data are limited, and the effect of AD severity on neuropsychiatric outcomes requires further characterization. OBJECTIVES To determine the risk of several major neuropsychiatric conditions in children with AD. METHODS We analysed UK health records data in a population-based cohort study. Each patient <18 years old with AD was matched to up to five unaffected patients on age, practice and index date. Treatments served as proxies for AD severity, which was analysed in a time-updated manner. Outcomes were incident anxiety, depression, bipolar disorder, schizophrenia, ADHD, autism, obsessive-compulsive disorder (OCD), suicidal ideation or attempt, and completed suicide. RESULTS A total of 409,431 children with AD (93.2% mild, 5.5% moderate, 1.3% severe) were compared to 1,809,029 children without AD. In Cox regression models adjusted for age, sex, socioeconomic status and other atopic comorbidities, no statistically significant relationships were observed between AD and incident anxiety (HR 1.01, 95% CI 0.99-1.03), ADHD (1.02, 0.97-1.06), autism (1.02, 0.98-1.06), bipolar disorder (1.08, 0.85-1.36), suicidal ideation/attempt (0.98, 0.95-1.01) or completed suicide (0.85, 0.64-1.14). Children with AD were less likely to develop depression (0.93, 0.91-0.95) or schizophrenia (0.72, 0.54-0.95) but more likely to develop OCD (1.26, 1.16-1.37). However, there was substantial variation by AD severity and age in both the direction and magnitude of effect for many of the neuropsychiatric conditions examined. CONCLUSIONS The was no substantial impact of AD on the overall risk of many neuropsychiatric conditions in children, but disease severity and age may be important modifying factors. Additional research is needed to further dissect the complex relationship between paediatric AD and neuropsychiatric comorbidities.

Abstract
Patients with versus without atopic dermatitis may have a greater risk of cardiovascular events, and the risk increases with severity of atopic dermatitis. The incidence of cardiovascular events in the population of patients with moderate-to-severe atopic dermatitis is largely unknown. This retrospective study evaluates incidence rates of cardiovascular events in patients aged ≥12 years with moderate-to-severe atopic dermatitis in a cohort of Kaiser Permanente Northern California health care system members without recognized risk factors for adverse events. Patients with moderate-to-severe atopic dermatitis, as defined by dermatologist-rendered code and prescription history between 2007 and 2018, were included. Major adverse cardiovascular events, venous thrombotic events, deep vein thrombosis, and pulmonary embolisms were identified via International Classification of Diseases codes. Stratification variables included age, sex, race, smoking history, and diabetes. Incidence rates per 1000 person-years were calculated by the number of patients with an incident event divided by the total person-years of observation. Among 8197 patients with moderate-to-severe atopic dermatitis, incidence rates per 1000 person-years (95% confidence interval) for major adverse cardiovascular events, venous thrombotic events, deep vein thrombosis, and pulmonary embolism were: 2.6 (2.1-3.2), 2.0 (1.5-2.5), 1.6 (1.2-2.1), and 0.7 (0.5-1.0), respectively. Incidence rates for all events were higher for older versus younger patients, patients with versus without diabetes, former smokers versus patients who had never smoked, and men versus women, except for pulmonary embolisms, which were higher in women. This study estimated the incidence of cardiovascular events in patients with moderate-to-severe atopic dermatitis and provides valuable information for clinicians.

Abstract
BACKGROUND Staphylococcal and herpes simplex virus (HSV) infections are commonly recognized in atopic dermatitis (AD) but less is known about other types of infections. OBJECTIVES To determine the risk of herpesvirus infections, serious infections, and opportunistic infections in patients with AD. METHODS We conducted a population-based cohort study using UK-based electronic medical records data. Patients with AD were each matched to up to 5 unaffected patients on age, practice, and index date. AD severity was defined using treatments. The outcomes were incident herpesvirus infections (cytomegalovirus [CMV], Epstein-Barr virus [EBV], HSV, or varicella zoster virus [VZV]), serious infections, and opportunistic infections. RESULTS 409,431 children and 625,083 adults with AD were matched to 1,809,029 children and 2,678,888 adults without AD, respectively. In adjusted Cox regression models, children and adults with AD had 50-52% greater risk of HSV and 18-33% greater risk of VZV, with risk increasing in parallel with AD severity. CMV risk was elevated among children with AD (HR 2.50 [1.38-4.54]) and adults with severe AD (4.45 [1.76-11.25]). Patients with AD had 26-40% increase in risk of serious infections, with severe AD carrying greatest risk. Although rare, opportunistic infections were not associated with AD in children but were associated with all severities of AD in adults (overall HR 1.31 [1.20-1.42]). All estimates remained consistent after excluding patients receiving immunosuppressive treatments for AD. CONCLUSIONS AD is significantly associated with herpesvirus infections, serious infections, and opportunistic infections in a dose-responsive manner with severity. AD may increase susceptibility to infections exclusive of immunosuppressive medications.

Abstract
BACKGROUND AND AIMS Previous studies have not addressed a fundamental component of a food addiction disorder: the compulsive relationship between eating and potentially positively reinforcing foods. We aimed to evaluate the association between food consumption and food addiction. METHODS We conducted cross-sectional analyses merging data from the Nurses' Health Study (n = 58,625) and Nurses' Health Study II (n = 65,063), two prospective cohort studies of female nurses in the United States. Diet was assessed in 2006-2007 using a food frequency questionnaire, and food addiction was assessed in 2008-2009 using the Modified Yale Food Addiction Scale. RESULTS The prevalence of food addiction was 5.4%. The odds of food addiction were strongest among nurses consuming 5+ servings/week (compared with <1 serving/month) of hamburgers (multivariable odds ratio (MVOR) 4.08; 95% CI, 2.66-6.25), French fries (MVOR, 2.37; 95% CI, 1.59-3.51) and pizza (MVOR, 2.49; 95% CI, 1.67-3.69). Consumption of red/processed meat, low/no fat snacks/desserts, and low calorie beverages was positively associated with food addiction, while consumption of refined grains, sugar-sweetened beverages and fruits, vegetables, and legumes was inversely associated with food addiction. CONCLUSIONS This epidemiologic study was the largest to examine food consumption and food addiction. Food addiction was positively associated with consumption of many hypothesized positively reinforcing foods that include a combination of carbohydrates and fats such as snacks, "fast foods," and candy bars. However, it was inversely or not associated with certain sweet foods, refined grains, and sugar-sweetened beverages, which is consistent with literature suggesting that carbohydrates (without other ingredients) are less associated with food addiction. Longitudinal analyses will help untangle the temporal order between food consumption and food addiction, as some relationships in our analyses were difficult to interpret due to the cross-sectional design.

Abstract
Asthma and suicide attempts are leading causes of morbidity and mortality among adults in the United States. The objective of this study was to investigate the relationship between asthma and suicidal ideation and suicide attempt among adults in the United States, and to examine whether timing of asthma, mood disorders, poverty, allergies, cigarette smoking and sex differences confound these relationships. Data were drawn from the Third National Health and Nutrition Examination Survey (NHANES III), a representative sample of adults (N = 6584) in the United States. Logistic regression analyses were used to examine the relationships between current and former asthma and suicidal ideation and suicide attempt, adjusting for demographics, poverty, smoking, allergies and mood disorders. Current asthma is significantly associated with an increased likelihood of suicidal ideation (OR: 1.77, CI: 1.11, 2.84) and suicide attempt (OR: 3.26, CI: 1.97, 5.39), after adjusting for mood disorders, smoking, poverty and demographics. There does not appear to be a significant relationship between former asthma and suicidal ideation or suicide attempt. These findings confirm and extend previous evidence by showing that the link between asthma and suicide-related outcomes is evident among adults in a representative sample and that this relationship persists after adjusting for a range of variables. This study may provide an empiric foundation for including asthma in the clinical assessment of suicide risk.

Abstract
BACKGROUND Although pregnancy is often viewed as a unique opportunity to engage women in positive health changes, including smoking cessation, it is not clear whether, or to what extent, smoking cessation initiated during pregnancy persists long term after pregnancy. The purpose of the present study was to investigate the relation between smoking cessation during pregnancy and smoking status three years later. METHOD Data were drawn from the National Epidemiologic Survey of Alcohol and Relation Conditions (NESARC), a nationally representative sample of over 40,000 adults in the United States. Multiple logistic regression analyses were conducted to examine the relation between smoking cessation during pregnancy and odds of smoking three years later. Smoking status at follow-up of women who continued smoking during pregnancy and women who never smoked was also examined. Analyses controlled for demographic differences. RESULTS Smoking cessation during pregnancy was not significantly related to smoking status three years later. However, continued smoking during pregnancy was associated with significantly increased odds of smoking three years later, compared to smokers who were not pregnant at baseline. Among non-smokers, pregnancy at baseline was associated with a significantly decreased likelihood of smoking three years later, compared to women who were not pregnant at baseline. CONCLUSIONS The present study uniquely extends previous research on smoking cessation during and following pregnancy. The results call for increased efforts to develop interventions that help new mothers develop and maintain abstinence from smoking.

Abstract
INTRODUCTION Previous studies have shown links between anxiety and depression and chronic obstructive pulmonary disease (COPD), but little is known about possible mechanisms of this association. The current study examined whether the observed relationship between anxiety and depression and COPD is explained by confounding due to cigarette smoking and lifetime nicotine dependence. METHODS Data were drawn from the National Comorbidity Survey Replication, a community-based representative sample of adults in the United States. RESULTS Analyses suggest that the association between anxiety disorders and COPD appears to be largely explained by confounding by former cigarette smoking and lifetime nicotine dependence. The association between mood disorders and COPD appears to be largely explained by confounding by lifetime nicotine dependence. CONCLUSIONS These findings provide initial evidence suggesting that the association between anxiety, depression, and COPD may be at least partly attributable to confounding by cigarette smoking and nicotine dependence. Efforts toward prevention of chronic lung disease may be more effective if treatment and prevention efforts aimed at smoking cessation address mental health problems.

Searching one or two databases was insufficient for meta-analysis of observational studies. J Clin Epidemiol 2005; 58:867-73. [PMID: 16085190 DOI: 10.1016/j.jclinepi.2005.03.004] [Citation(s) in RCA: 102] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2004] [Revised: 02/17/2005] [Accepted: 03/08/2005] [Indexed: 11/27/2022]
Abstract
OBJECTIVE To address methodologic issues in searching for observational studies by presenting database search methods and results. STUDY DESIGN AND SETTING Results of two literature searches for publications reporting on observational studies of alcohol consumption and the risk of breast cancer and large bowel cancer were compared, to evaluate the sensitivity of various bibliographic databases and search strategies, including hand-searching reviews and meta-analyses. RESULTS The target sensitivity of 90% of publications in the breast cancer search was achieved by starting with Medline, then adding Biosis, Embase, and SCI EXPANDED-SSCI, which provided a total of 72 (91%) of the 79 relevant publications. To reach a similar 89% sensitivity for large bowel cancer, at least Biosis, Dissertation Abstracts Online, Embase, ETOH, and Medline had to be searched, with the addition of hand search of reviews and meta-analyses. CONCLUSION Limiting a search to one or two databases when conducting meta-analyses of observational studies will not provide a thorough summary of the existing literature. The findings support recommendations to implement a comprehensive search of electronic databases and the reference lists of recent review articles and meta-analyses.
