A scientist's position within the ranking is determined by their D-index (Discipline H-index), a metric that focuses exclusively on the impact and volume of papers and citations pertinent to the specific discipline under examination—Medicine in this instance. This ensures that the evaluation accurately represents a researcher’s influence within their specialized field, rather than their general scholarly footprint.
Scope of Research and Eligibility Criteria
The ranking process involved the examination of 188,153 scientist profiles identified across a broad spectrum of bibliometric data sources and spanning all research disciplines. Specifically, for this edition, 1,188 scientists conducting research in Medicine were rigorously analyzed.
To qualify for inclusion in the Medicine ranking, a scientist was required to meet the following criteria:
- Their D-index within Medicine needed to be at least 70.
- A majority of their tier publications must reside in the field of Medicine, ensuring subject-matter relevance.
- Recognition through awards and notable achievements in Medicine was also considered as a supplementary factor.
The D-index threshold is dynamically set, increasing in increments of 10 in accordance with the estimated number of scholars within each discipline. This approach not only adjusts for disciplinary scale but also ensures that the top 1% of leading scholars in each field are incorporated into the list. Additionally, to maintain disciplinary consistency and accuracy, the D-index must not differ from the general H-index by more than 30%, which confirms that a researcher’s core impact remains centered in Medicine.
Verification and Methodological Rigor
At Research.com, we recognize that raw bibliometric data alone cannot comprehensively evaluate the scientific output or influence of scholars. To address this, all scientist profiles included in the ranking underwent meticulous manual verification and cross-correlation against publications indexed in a wide range of trusted, high-quality sources. This process mitigates errors arising from data inconsistencies and affiliation ambiguities.
While not directly influencing a researcher’s ranking position, the number of publications in prominent journals and conference proceedings is acknowledged as a valuable secondary indicator of a scientist's contribution to their discipline.
The positions in the ranking are established through the calculated D-index derived from data gathered predominantly from OpenAlex and CrossRef, which are among the most prominent, respected, and widely used bibliometric databases accessible to the scholarly community worldwide.
