RAF: risk allele frequency; OR: odds ratio. Odds ratio are presented with respect to risk allele that are highlighted as underlined text. β: change in Z score of BMI per increase in risk allele; SE: standard error. Combined analysis was performed by combining raw genotype data from stage 1 and stage 2. Meta-analysis was performed by combining the summary estimates (OR/β, 95%CI and S.E). No heterogeneity in two study population was observed (P value for Cochrane's Q statistic = 0.48 and Î2 heterogeneity index = 0.0). *OR/β and P value for fixed effect meta-analysis.
