Publication Trends of Nonobstetric Brachial Plexus Injury Research: A Bibliometric Analysis.

Objective To evaluate publication trends in nonobstetric brachial plexus injury research. Methods In September 2020, Scopus was searched for articles on nonobstretric brachial plexus injury. Citation count, year of publication, country of corresponding author and its income category, destiny journal and its 5-year impact factor (IF), and research type were retrieved. Results The analysis comprised 1245 articles. Mean number of citations per article was 18.01 (95% confidence interval 16.46–19.55). Mean IF was 3.60 (95% confidence interval 3.25–3.95). The 5 most prolific journals had an IF Conclusions While high-income countries still represent the majority of publications, the contribution of researchers from middle-income countries is increasing. The most common destiny journals are field specific, with a relatively low IF. Although most articles are primary research, a representative portion have a shallow level of evidence (case reports and narrative reviews).
