A university’s position in the ranking is determined based on the sum of D-indexes (Discipline H-index) of all scholars affiliated with the institution whose main area of publication is Medicine. The D-index is an exclusive metric, encompassing only publications and citation impact within the specific discipline of Medicine, ensuring subject-relevant, granular evaluation of academic influence.
Scope of Research and Scholar Selection Criteria
For this edition, 279,971 scientist profiles were identified and analyzed across a range of bibliometric sources. Of these, 72,221 scientists specializing in Medicine were closely examined for inclusion in the ranking.
Key criteria for selection included a qualifying D-index threshold of 70; in addition, the majority of each candidate’s high-impact publications were required to be in Medicine. Distinction was also afforded to scientists’ awards and achievements in the field. The threshold for the top researchers was dynamically set, increasing in increments of 10, tailored to the total number of scholars in each discipline, yet ensuring incorporation of the top 1% of proven leaders in every field. Furthermore, a proximity of 30% or less was required between a scientist’s overall H-index and their discipline-specific D-index to affirm field-specialization.
Scientist awards and notable achievements in Medicine further influenced candidacy, promoting recognition of qualitative contributions beyond mere citation counts.
Verification Practices and Evaluation Integrity
Recognizing the limitations inherent in raw bibliometric data, the Research.com team undertook manual verification of all scientist profiles. This involved thorough cross-correlation against a broad spectrum of authoritative publication sources to maximize accuracy and credibility.
While the number of papers published in leading journals and conferences is not a direct determinant of a researcher’s standing in the Research.com ranking, it represents an important supplementary indicator of impact within the scientific community.
A researcher’s ranking position is anchored in their H-index, derived from the latest, concordant data compiled via OpenAlex and CrossRef – internationally renowned, extensively-validated bibliometric databases. The comprehensiveness and reliability of these datasets reinforce the validity of all outputs.
