A university’s position in the ranking is determined by the aggregate D-index (Discipline H-index) of all ranking scholars affiliated with that institution, whose primary publication area is Medicine. The D-index is designed to reflect only the publications and citation data within the Medicine discipline, ensuring that institution and researcher contributions are assessed within their relevant field of expertise.
Scope of Research
To establish a precise and reliable Medicine university ranking, 279,971 scientist profiles were examined across a broad constellation of bibliometric data sources. Out of these, 72,221 scientists specializing in Medicine were further analyzed for eligibility.
The principal eligibility threshold was set at a D-index of 70 for each scientist, with the additional stipulation that a majority of their high-tier publications must be in the field of Medicine. Recognizing well-rounded achievement, a scientist’s awards and contributions in Medicine were also considered. The D-index qualifying bar for top researchers is fine-tuned in increments of 10, attached to the overall number of scholars estimated for each discipline, guaranteeing the inclusion of the top 1% of leading experts.
Moreover, to ensure discipline-specific expertise, there is a required proximity of 30% or less between a scientist’s general H-index and their D-index. This further eliminates potential dilution by multi-disciplinary publication and focuses on domain leadership. Additional recognitions—such as domain-specific awards—also play an evaluative role in the ranking.
Additional Verification and Quality Control
The Research.com team is acutely aware that raw bibliometric data alone cannot fully capture the breadth and depth of a scholar's impact. Accordingly, all shortlisted scientist profiles underwent manual verification and cross-verification against publications in a diverse array of trusted sources. While the sheer quantity of papers published in leading journals and at major conference proceedings is not a direct metric in determining position within the Research.com ranking, it is recognized as a valuable secondary indicator of a scientist’s sustained contribution to the Medicine discipline.
The ranking is fundamentally anchored in each researcher's H-index, as determined by datasets sourced from OpenAlex and CrossRef—the leading and most robust bibliometric databases available to the research community.
