* χ

^{2}test for overall comparison between diabetes population and control group 1 and control group 2 populations.†

*P*values and their odds ratios for genotypes were calculated by logistic regression analysis.‡

*P*values for multivariate analyses were adjusted for sex, age (age at onset of type 2 diabetes), and BMI.
