Abstract
INTRODUCTION: Evidence from Cochrane systematic reviews has significantly impacted clinical practices across diverse disciplines and is widely integrated into international guidelines. To date, there are no bibliometric analyses of Cochrane's publications. METHODS: The search encompassed the Scopus database from inception to May 2024, with results limited to studies published by the Cochrane Database of Systematic Reviews. The analysis examined annual trends and publication volumes, citation patterns, contributing countries, authors, institutions, funding sources, and common keywords. Scopus' built-in analytical tools, the bibliometrix package in RStudio, and VOSviewer software facilitated the analysis of the results. RESULTS: A total of 12,150 systematic reviews were eligible. There was a fluctuating pattern in publication and citation trends within Cochrane reviews, with a decline in both metrics since 2016. Contributions mainly came from high-income countries, their institutions, and authors residing there, with significant government funding supporting publications in these regions. The United Kingdom (27%), Australia (10%), and the United States (9%) had the greatest contributions among other countries, respectively. Furthermore, the demographic emphasis in Cochrane reviews was concerned with female and male participants as well as children and adult populations, hinting at the potential underrepresentation of minor gender identities and older adults in the synthesis of evidence. CONCLUSION: Cochrane should actively involve researchers and experts from low- and middle-income countries in evidence synthesis, ensure underrepresented and low-resource regions are included in its emerging Evidence Synthesis Units and Thematic Groups, and prioritize the inclusion of geriatric populations and sexual and gender minorities in its evidence to enhance inclusivity and global representation.
