Data Sources and Citation Metrics
The 5th edition of the Research.com Best Medicine Scientists in Switzerland Ranking is grounded in comprehensive bibliometric data primarily sourced from OpenAlex and CrossRef, supplemented by multiple other authoritative data repositories. The citation-based metrics used to determine the ranking were compiled through a rigorous data collection process conducted on 2026-01-12. A scientist’s position within this ranking is determined by their Discipline H-index, or D-index, a metric that exclusively considers publications and citation metrics relevant to the specific discipline under examination—in this case, Medicine.
Scope of Research and Eligibility Criteria
The ranking is based on an analysis of 188,153 scientist profiles derived from diverse bibliometric data sources across all scientific domains, with a focused evaluation of 307 scientists specializing in Medicine. To qualify for inclusion, a scientist must have a D-index of at least 70, and a majority of their tier publications must be concentrated within the field of Medicine. In addition to bibliometric performance, awards and achievements pertinent to Medicine were also taken into account to ensure recognition of impactful contributions.
The threshold for the D-index is calibrated in increments of 10 relative to the estimated total number of scholars within each discipline. This approach guarantees inclusion of the top 1% of leading experts in the field, maintaining a competitive and fair representation of outstanding researchers. Moreover, a requisite condition for eligibility is that the disparity between a scientist’s general H-index and their Medicine-specific D-index remains at 30% or less, ensuring a strong alignment between overall scholarly impact and expertise within the discipline.
Verification and Validation Practices
Understanding that raw bibliometric data alone cannot provide an absolute evaluation of scholarly output, the Research.com team has implemented meticulous verification practices. Each scientist’s profile was manually reviewed and cross-correlated against publications verified through an extensive range of reputable sources. This manual verification complements the quantitative metrics and serves to enhance the accuracy and credibility of the ranking.
While the ranking itself is determined solely by the D-index calculated from data provided by OpenAlex and CrossRef—two of the most prominent and trusted bibliometric databases accessible to the global research community—the number of publications in leading journals and conference proceedings is acknowledged as an important secondary indicator of a researcher’s influence within Medicine.
