  1. aEffect size. b For SNPs for which effect size was greater than 0.5, required sample size to achieve 80% power was calculated. c Power given the actual number of genotyped samples. If the actual number of genotyped samples exceeded the required sample size, SNPs are marked in underlined bold text.
