A scientist's position in the ranking is determined by their D-index (Discipline H-index), a refined metric that captures only those publications and citation metrics directly relevant to the discipline under examination—in this case, Medicine. This focused approach ensures the ranking accurately reflects scientific impact within the specific research domain.
Scope of Research and Eligibility Criteria
In formulating the ranking, a total of 188,153 scientist profiles identified from a variety of bibliometric data sources across all disciplines were examined. Within this extensive dataset, 26 scientists specializing in Medicine were evaluated in detail. To qualify for inclusion in the ranking, a scientist’s D-index was required to be at least 70, with the majority of their tier publications concentrated in the field of Medicine. Additionally, awards and achievements specific to the medical sciences were considered as supplementary factors in the evaluation process.
The threshold for the D-index to qualify top researchers is calibrated in increments of 10, relative to the estimated total number of scholars per discipline. This method ensures coverage of the top 1% of leading scholars in each field while maintaining academic rigor and inclusivity. Furthermore, there is a criterion that the proximity between a scientist’s general H-index and their D-index should not exceed 30%, thereby confirming a strong disciplinary focus in their research output.
Verification and Evaluation Practices
Research.com is acutely aware that raw bibliometric data, while valuable, should not be singularly relied upon as an absolute measure of scholarly output. Accordingly, every scientist profile included in the ranking was manually verified and cross-correlated with publications indexed in a broad array of trustworthy sources. This meticulous verification process enhances the reliability and credibility of the ranking.
It is important to note that, although the number of papers published in prominent journals and conference proceedings does not directly influence a researcher’s position in the ranking, it serves as a valuable secondary signal of scientific contribution within a specific field.
The final ranking position is derived using each researcher's D-index, calculated from information aggregated from OpenAlex and CrossRef, the most prominent and widely trusted bibliometric databases accessible to the global research community.
