We built a database with 28 dichotomous disease phenotypes (Table S1), with data coming from 206 European, 71 East Asian and 16 African GWAS. Several features of interest were recorded for each GWAS: first author, journal, year of publication, genetic ancestry, sample size in GWAS stage, total sample size in replication stage, array genotyped, genomic control factor in GWAS stage (if available), use of imputed SNPs (Y/N) and number of genomic regions achieving genome-wide significance in the initial and final stage (Table S2). The publications corresponding to each GWAS were downloaded from the respective journals.
