Abbreviations: OR, odds ratio; CI, confidence interval; BMI, body mass index; WC, waist circumference.

OR and 95% CI are reported for genotype risk score quartiles using logistic regression under the following models: model 1, adjusted for age and sex; model 2, adjusted for age, sex and BMI; and model 3, adjusted for age, sex, BMI and WC.

P values<0.05 are shown in bold.
