Data are only given for the SNPs associated with maximum BMI in adulthood and/or maximum BMI z-score in childhood with p≤0.05 in full-heritage Pima Indians (n as indicated). R: risk allele; N: non-risk allele; RAF: risk allele frequency. The risk allele is defined as the allele with higher risk for BMI in Europeans. Beta and p value are adjusted for age, sex, birth year and the first five genetic principal components. BMI is loge-transformed before analyses to approximate a normal distribution. Data for meta-analysis of GIANT in Europeans are derived from the public database and beta coefficients are expressed in SD units by inverse Gaussian transformation of BMI. For comparison with beta coefficients in Europeans, maximum BMI in Pima Indians is also transformed using an inverse Gaussian transformation; results are presented as beta (SD) and used in heterogeneity analyses. I2 represents the percentage of variance in the effect attributable to heterogeneity between Pima Indians and Europeans, and Phet is the p value for the null hypothesis that the two betas are equal.
A proxy SNP was used for genotyping (listed in Table S1). Bold values: p ≤ 0.05.
