Index SNPs for distinct T2D association signals at four susceptibility loci on the basis of aggregation of summary statistics from 18 GWAS (22,086 cases and 42,539 controls) from diverse populations using: (i) MR-MEGA meta-regression accounting for ancestry with three axes of genetic variation as covariates; and (ii) reported results from fixed-effects meta-analysis
