^{a }6 Excluded nonsignificant variables: a) percentage of intronic SNPs in the gene from each association, b) total number of studies of each association, c) total number of studies performed in Europe, d) total number of studies performed in East Asia, e) average study sample size of each association, and f) average year of study performance in each association ^{b }Conservative set contains those associations that at least in one continent have a replicability index of 50% ^{c }Tol = Tolerance
