The bibliometric data forming the basis for the citation-based metrics of the ranking were collected as of 2024-11-27. A university's position in the final ranking is determined through the sum of D-indexes (Discipline H-index) of all affiliated scholars in the field of Medicine. Only those whose primary publication area is classified as Medicine are considered. The D-index is a specialized metric that includes exclusively the publications and citations within the given discipline, thus providing a focused and reliable measure of research impact in Medicine.
Scope of Research and Selection Criteria
The ranking evaluates a vast scope of individual research contributions. In total, 279,971 scientist profiles across a variety of disciplines were scrutinized from numerous bibliometric data sources. Specifically, 72,221 scientists classified in Medicine were analysed in-depth.
To ensure the highest level of selectivity, a qualifying D-index threshold of 70 was set for scientists to be considered in Medicine, with a major portion of their top-tier publications required to be in this field. In measuring excellence, each discipline’s D-index threshold for top researchers was set with an increment of 10, calibrated against the estimated total number of scientists per discipline, while guaranteeing that the top 1% of leading scholars were included in the ranking.
Additionally, proximity between a scholar’s general H-index and their D-index must not exceed 30%, ensuring that the evaluated impact is tightly focused on their work in Medicine. Scientists' distinguished awards and achievements in Medicine also contributed to selection, reflecting both quantitative and qualitative measures of academic excellence.
Verification and Data Validation Practices
Aware that bibliometric data alone cannot fully capture the breadth and depth of a scholar’s contributions, the Research.com team implemented rigorous manual verification processes. Every scientist’s profile was manually checked and cross-verified against trusted publication sources to confirm accuracy and integrity.
Although the volume of publications in prestigious journals and conference proceedings is not a direct ranking factor in the Research.com methodology, it is acknowledged as a significant secondary indicator of a researcher’s contribution to the field. Institutional ranking positions have been established by leveraging each researcher’s H-index sourced from OpenAlex and CrossRef—databases widely regarded within the scholarly community for their reliability and comprehensiveness.
