Scientific Collaboration across Time and Space: Bibliometric Analysis of the American Journal of Neuroradiology, 1980-2018

The top 100 most-cited articles on adult spinal deformity: The most popular topics are still sagittal plane parameters and complications

Purpose

This study aimed to summarize the characteristics of the 100 most-cited articles on adult spinal deformity (ASD) and to analyze past and current research hotspots and trends.

Methods

Literature searches (from inception to 28 April 2022) using Web of Science databases were conducted to identify ASD-related articles. The top 100 most-cited articles were collected for further analysis. Meanwhile, author keywords from articles published in the last 5 years were selected for further analysis.

Results

The top 100 most-cited articles on ASD were selected from 3,354 papers. The publication year ranged from 1979 to 2017, and all papers were written in English. The citation count among them ranged from 100 to 1,145, and the mean citation number was 215.2. The foremost productive first author was Schwab F. University of Washington had the largest number of publications. The United States of America had the largest number of published articles (n = 84) in this field. Spine was the most popular journal. Complications were the most studied themes. The visualization analysis of author keywords from the literature in the recent 5 years showed that complications, sagittal plane parameters, and surgical techniques are still the research hotspots, and minimally invasive surgery will continue to develop rapidly.

Conclusion

Based on a comparative analysis of the results of bibliometric and visualization, complications and sagittal plane parameters are still the major topics of research at present and even later, and minimally invasive surgery has a growth trend in this field of ASD.

Geographic Trends in Publications and Submissions in Radiology Journals: Decade Report (2010 - 2020)

RATIONALE AND OBJECTIVE

The Radiology Research Alliance (RRA) of the Association of University Radiologists (AUR) organized a task force to quantify geographic changes in submissions to and publications within radiology journals over time.

MATERIALS AND METHODS

Twenty journals were selected: 7 US-based general, 4 European-based general, and 9 subspecialty radiology journals. Journals were solicited for submissions and publications based on country of origin from 2010 -2020. Regression models assessed changes over time across countries, and by continent, with an emphasis on the US and China, for each journal category.

RESULTS

There were 104,679 publications and 92,446 submissions from 149 countries. Overall, there were significant increases in numbers of publications from Asia (R² = 0.66, p <0.01), and specifically, China (R² = 0.87, p <0.01). For US journals, there were increased numbers of publications from Asia (R² = 0.72, p <0.01) and China (R² = 0.98, p <0.01), but decreased numbers from North America (R² = 0.41, p = 0.03). For European journals, there were increased numbers of publications from Asia (R² = 0.79, p <0.01), North America (R² = 0.75, p <0.01), and China (R² = 0.82, p <0.01). For subspecialty journals, there were increased numbers of publications from North America (R² = 0.38, p = 0.04) and China (R² = 0.73, p <0.01). There was an acute COVID spike in submissions during 2020, with a continuous increase most notable in China (R² = 0.96, p <0.01).

CONCLUSION

In the last decade, the numbers of submissions to and publications within general and subspecialty US and European radiology journals have generally increased around the world, with the largest growth in Asia and in particular China.
