A scientist's position in the ranking is determined by their D-index (Discipline H-index), a refined metric that considers only the papers and citation metrics pertinent to the examined discipline—in this case, Medicine. This discipline-specific focus ensures a more accurate reflection of each researcher's impact within their field.
Scope of Research and Selection Criteria
The ranking analysis commenced with the examination of 188,153 scientist profiles extracted from diverse bibliometric data sources spanning all academic disciplines. Within this dataset, four scientists from the field of Medicine in Saudi Arabia were specifically identified and evaluated.
To qualify for inclusion, scientists were required to have a D-index of at least 70. Furthermore, the majority of their tier publications had to be within the Medicine discipline, affirming the relevance of their research contributions. Awards and significant achievements in the field of Medicine also constituted a meaningful factor in the evaluation process.
The threshold for D-index consideration is dynamically set as increments of 10, scaled to the estimated number of scholars in each discipline. This method guarantees the inclusion of the top 1% of leading scholars per discipline, maintaining both rigor and representativeness. Additionally, qualifying scientists must demonstrate a proximity of 30% or less between their general H-index and D-index, ensuring their core expertise aligns closely with the discipline evaluated.
Verification Practices and Methodological Transparency
The Research.com team recognizes that raw bibliometric data alone cannot fully capture the multifaceted nature of scholarly contributions. Accordingly, each scientist profile featured in this ranking underwent manual verification and cross-correlation against publications indexed across a wide spectrum of trustworthy sources to ensure accuracy and authenticity.
Although not factored directly into ranking positions, the number of publications in prominent journals and conference proceedings serves as a valuable secondary indicator of a scientist’s influence and involvement within their specialized area of research.
The final ranking positions are established exclusively by applying the D-index, leveraging data obtained from OpenAlex and CrossRef—the two most prominent and reliable bibliometric databases accessible to the global research community.
