A position in the ranking is determined by the sum of D-indexes (Discipline H-index) of all qualifying scholars affiliated with each institution, specifically those whose primary publication area is Medicine. The D-index uniquely accounts for publications and citation counts within the specified discipline, ensuring a precise focus on Medicine-specific scientific impact.
Scope of Research and Inclusion Criteria
The scope of the ranking is notable for its depth and inclusivity. An exhaustive profiling process examined 279,971 scientist profiles sourced from various bibliometric datasets. Out of these, 72,221 scientists were analyzed in the Medicine discipline alone.
To ensure rigor, only scientists surpassing a D-index threshold of 70 were eligible, with the majority of their key publications required to be in Medicine. Scientists’ awards and achievements in Medicine were also considered to reflect qualitative impact alongside quantitative measures. The D-index threshold for top researcher consideration incrementally increases by 10 depending on the total number of scholars within each discipline, ensuring that the top 1% of leading scholars are represented. Moreover, a proximity of 30% or less is mandated between a scientist’s general H-index and their D-index, reinforcing discipline-specific recognition.
Comprehensive Verification Practices
The creators of this ranking recognize that raw bibliometric data alone cannot wholly capture the value and nuances of scholarly contributions. Accordingly, all scientist profiles underwent manual verification and were cross-referenced with publications from reputable sources to affirm data integrity.
While not a determining factor for final ranking position, the number of papers published in prominent journals and conference proceedings serves as a significant indicator of a researcher’s influence and contribution within their area of expertise. The final position in the ranking is established using each researcher’s H-index, as captured by OpenAlex and CrossRef, the leading bibliometric databases available to the scientific community.
