A university’s position in the ranking is determined by the aggregate of D-indexes (Discipline H-index) of all ranking scholars affiliated with that institution, whose principal published output falls within the domain of Medicine. The D-index calculation is exclusively discipline-specific, taking into account only those publications and citations pertinent to Medicine.
Scope of Research and Ranking Criteria
The scope of research conducted for this ranking is both extensive and precise. In the initial phase, 279,971 scientist profiles identified from a broad array of bibliometric databases were examined. Out of these, 72,221 scientists specializing in Medicine were scrutinized in detail.
The selection threshold was stringent: a minimum D-index of 70 was required for consideration, with the majority of each scientist’s leading publications necessitated to be in Medicine. Additionally, the scientist’s awards and achievements in the field were factored into the evaluation. Notably, the D-index threshold for recognizing top researchers is adjusted in increments of 10, tailored to the total number of scholars identified within each respective discipline—a system designed to ensure that the uppermost 1% of leading scholars are included in the list.
To maintain discipline fidelity, a maximum proximity of 30% is enforced between a scientist’s general H-index and their D-index. The assessment equally integrated recognition of exceptional scientific awards and achievements relevant to Medicine, providing a more holistic view of scholarly impact and leadership in the field.
Verification and Quality Assurance Practices
Research.com recognizes that while bibliometric data provide essential insights, they are not absolute indicators of scientific merit. Therefore, all scientist profiles incorporated into the ranking underwent rigorous manual verification and were cross-referenced against a wide range of trusted publication sources.
Although the sheer number of publications in top journals and conference proceedings is not a direct criterion influencing placement in the Research.com ranking, these metrics do serve as valuable secondary signals regarding a scientist's research contributions. The core metric determining ranking position remains each researcher’s H-index, as validated through data from OpenAlex and CrossRef, the preeminent bibliometric databases widely trusted within the academic community.
