A scientist’s position in the ranking is determined using the D-index (Discipline H-index), a refined metric that considers only those papers and citations relevant to the specific discipline under examination—in this case, Medicine. This focus on disciplinary relevance allows for a more accurate and meaningful assessment of impact within the field.
Scope of Research
The scope of the ranking encompasses an extensive pool of 188,153 scientist profiles identified across all disciplines from a wide range of bibliometric sources. Within this dataset, profiles of scientists specializing in Medicine were scrutinized to identify those who meet stringent qualification criteria. To qualify for inclusion in the Medicine ranking, a scientist’s D-index must be at least 70, and a majority of their tier publications must reside within the medical discipline.
In addition to bibliometric thresholds, scientists’ awards and recognized achievements in Medicine were also factored into the evaluation, providing a qualitative dimension to the ranking.
The D-index thresholds are established in increments of 10, calibrated based on the total number of scholars estimated per discipline. This methodology ensures the inclusion of the top 1% of leading researchers in each field. Furthermore, a proximity constraint of 30% or less between a scientist’s overall H-index and their disciplinary D-index is maintained to confirm focus and expertise within Medicine.
Verification and Validation Practices
Recognizing that raw bibliometric data alone cannot serve as an absolute measure of scholarly output, the Research.com team undertook extensive manual verification of all scientist profiles. Each profile was cross-correlated against publications indexed in a broad spectrum of reliable and trustworthy sources to ensure accuracy and integrity.
Although not a contributing factor to position in the ranking, the number of papers published in prominent journals and major conference proceedings has been closely considered as a valuable secondary signal of a scientist’s overall contribution to their area of research.
Ultimately, position within the ranking is established using the D-index derived from authoritative bibliometric information from OpenAlex and CrossRef, two of the most prominent and widely respected databases within the global research community.
