How We Rank

MDRPedia rejects reputation-based surveys. Our Impact Quotient is calculated using a transparent, data-driven algorithm.

Data Sources

We aggregate from PubMed, Scopus, ClinicalTrials.gov, and verified hospital registries. Our crawlers index 30,000+ journals daily.

Weighted Citations

Not all citations are equal. A Lancet citation weighs 50x more than a predatory journal. Lead authorship scores higher than co-authorship.

Honor Integration

Nobel laureates and national honor recipients receive floor protection. Verified awards contribute to the final score.

Tier Classifications

TITAN Top 0.01%

Living legends who have invented procedures, written definitive textbooks, or led global health initiatives.

ELITE Top 1%

National leaders and department chairs at major academic medical centers. The "doctors' doctors."

MASTER Top 3%

High-volume, high-outcome experts who anchor their local medical communities.
