Numbers of associations contained in different GWAS databases; statistics are over open-access papers

Database	Papers	Associations	Unique associations
GWAS Catalog	589	8384	>2026
GWAS Central	516	5914	>364
GWASkb (ours)	589	6231	>2777

Unique associations are contained in one database and in none of the others. Human curated databases (GWAS Catalog and GWAS Central) significantly differ in their scope. Our machine-compiled repository (GWASkb) automatically recovers a large fraction of known results and also finds a comparable number of unique associations
