A scientist's position within the ranking is determined exclusively by their D-index (Discipline H-index), a refined metric that evaluates a researcher's scholarly influence within a specific discipline. The D-index incorporates only those papers and citation counts directly related to the examined discipline, thereby providing a focused and accurate measure of domain-specific scientific contribution.
Scope of Research Considered
The ranking involved a rigorous examination of 188,153 scientist profiles compiled from various bibliometric data sources across all scientific disciplines. From this extensive pool, 47 scientists specializing in Medicine were specifically identified and evaluated.
- To qualify for inclusion in the Medicine ranking, a scientist’s D-index had to meet or exceed the threshold of 70.
- The majority of each qualifying scientist’s tier publications were required to be within the field of Medicine, ensuring discipline relevance and focus.
- Awards and achievements related to Medicine were also considered as supplemental factors reinforcing the scientist’s prominence in the field.
The D-index threshold is dynamically set with increments of 10 based on the estimated total number of scholars in each discipline. This approach guarantees that approximately the top 1% of leading scholars are incorporated into the ranking. Additionally, a proximity criterion is applied whereby the divergence between a scientist’s general H-index and their discipline-specific D-index must not exceed 30%, reinforcing consistency between overall impact and scholarly focus.
Additional Verification Practices
Recognizing that raw bibliometric data alone cannot fully capture the quality and nuance of scholarly output, the researchers behind this ranking undertake thorough manual verification of each scientist profile. This process involves cross-correlation against publications from a wide range of trustworthy and authoritative sources to confirm accuracy and relevance.
While factors such as the number of papers published in prominent journals and conference proceedings do not directly influence the ranking position, they serve as valuable secondary indicators of a scientist’s contribution to their specific field of study.
The final ranking is established using each researcher’s D-index derived from data sourced from OpenAlex and CrossRef, the foremost bibliometric databases available to the global research community due to their comprehensiveness and reliability.
