A scientist’s position in the ranking is determined using the D-index (Discipline H-index), a refined metric that specifically accounts for publications and citation impact within the examined discipline—in this case, Medicine. This approach allows for an assessment that reflects research influence within a targeted scientific field rather than across all disciplines.
Scope of Research and Inclusion Criteria
The ranking examined a total of 188,153 scientist profiles identified through an extensive analysis of bibliometric data sources across all disciplines. Within Medicine specifically, 1,000 scientists met the examination criteria and were considered for inclusion.
To qualify for the Medicine ranking, a scientist’s D-index must be at least 70. Additionally, the majority of their tier publications need to be focused on Medicine, reinforcing the discipline-specific nature of the evaluation. Consideration was also given to documented awards and achievements within the medical field, acknowledging excellence beyond bibliometric measures.
The threshold for the D-index is incrementally adjusted by steps of 10 relative to the estimated total number of scholars within each discipline. This dynamic setting ensures inclusion of the top 1% of leading researchers. Furthermore, the ranking method requires that the proximity between a scientist’s general H-index and their D-index be 30% or less, supporting consistency in research productivity and impact within the specified discipline.
Additional Verification and Methodological Rigor
The team behind the ranking recognizes that raw bibliometric data alone cannot serve as a definitive measure of a scholar’s output or influence. Consequently, all scientist profiles have undergone meticulous manual verification and cross-correlation against a diverse set of trustworthy sources. This manual curation enhances accuracy and reduces potential discrepancies or misattributions.
While not directly factored into the ranking position, the quantity of publications in prominent journals and major conference proceedings is considered a valuable secondary indicator of a scientist’s contribution to their domain. The position in the ranking fully emanates from the rigorously calculated D-index informed by data from OpenAlex and CrossRef, two of the most authoritative bibliometric repositories accessible to the global research community.
