BMI, body mass index; BP, blood pressure; HOMA-IR, homeostasis model assessment for insulin resistance; QUICKI, quantitative insulin sensitivity check index; TAG, triglycerides; HDL-C, high-density lipoprotein cholesterol; IL, interleukin; MAF, minor allele frequency; βBMI, Beta obtained under an additive model adjusted for BMI; P-valueBMI, P (P value) obtained under an additive model adjusted for BMI; CI, confidence interval; NA, not applicable. Linear regression analyses stratified by sex were performed under an additive model assuming TNMD locus escapes from the X-chromosome inactivation process. That is, while the female genotypes were coded 0, 1, or 2 according to 0, 1, or 2 TNMD SNP alleles, the genotypes for males were coded 0 or 1 according to 0 or 1 alleles. aAdjusted for age. bAdjusted for age and height.
