A scientist’s position within this ranking is determined by their D-index (Discipline H-index), a refined metric that exclusively considers papers and citation counts relevant to the specific discipline under examination—in this case, Medicine. This approach ensures the ranking accurately reflects the impact and contribution of researchers within the targeted field.
Scope of Research and Eligibility Criteria
The ranking process began with the examination of 188,153 scientist profiles aggregated from diverse bibliometric sources across all disciplines, including exactly 1,000 scientists specializing in Medicine. To qualify for inclusion in the Medicine-specific ranking, a researcher must have a D-index of at least 70, and a majority of their tier publications needed to be within the domain of Medicine. Additionally, recognition of awards and notable achievements in the medical field factored into the selection process.
The selection threshold for the D-index is dynamically set, increasing in increments of 10 based on the estimated total number of scholars within each discipline. This methodology ensures that approximately the top 1% of leading scholars are consistently incorporated into the ranking. Furthermore, to maintain disciplinary relevance, a candidate’s general H-index and D-index must align closely, with a maximum permitted variance of 30% or less, underscoring a focused research impact in Medicine.
Verification and Data Integrity
Research.com acknowledges that raw bibliometric data alone are insufficient as an absolute measure of scholarly output. To enhance the reliability and credibility of the ranking, all scientist profiles underwent comprehensive manual verification and were cross-validated against publications indexed in a broad range of trusted academic sources.
Although not contributing directly to the D-index or position in the ranking, the quantity of papers published in prominent journals and major conference proceedings serves as an important secondary indicator of a scientist’s research contribution within Medicine.
Positions in the ranking are established exclusively via the D-index calculated based on data from OpenAlex and CrossRef—two of the most prominent and widely trusted bibliometric databases available to the global research community.
