Bibliometric analysis of bibliometrics in biomedical science

This record contains supplementary material (S1) for the Opinion article “Emergence of bibliometric analysis in biomedical research: a macro-level perspective” .

Contents. The document reports the search strategy used to map published bibliometric studies in biomedical science. It covers two keyword strings (“Bibliometric Analysis AND Biomedical Science” and “Bibliometric AND Biomedical”), their full PubMed query translations, and record yields from four databases: PubMed, Scopus, OpenAlex and Scilit. The largest dataset (PubMed, “Bibliometric AND Biomedical”; n = 4,761 records) was analysed with the R package Bibliometrix 5.1.0 and its Biblioshiny 5.0 interface.

Key findings. Publications grew at an annual rate of 10.34%, with 14,649 contributing authors and an international co-authorship rate of 15.4%. Output rose steadily from the 1990s and sharply after 2023. Medicine and PLOS ONE were the most productive journals. Jazan University, Sichuan University and Central South University were the leading affiliations, and China and the USA were the leading countries.

Figures included: annual scientific production; most relevant sources, authors and affiliations; country production over time; and a country-collaboration world map.
