Abbreviations: MAF, minor allele frequency; HWF, Hardy-Weinberg equilibrium; OR, odds ratio; CI, confidence interval; df, degrees of freedom.
a Dominant model: TT + TC versus CC.
b Recessive model: TT versus TC + CC.
c P < .05
d Allele frequency: T versus C.
e Heterogeneity: Q = 0.812, df = 2, P = .666, fixed-effect model was adopted, test for overall effect: z = −1.318
f Heterogeneity: Q = 5.383, df = 2, P = .068, fixed-effect model was adopted, test for overall effect: z = −2.323
g Heterogeneity: Q = 0.022, df = 2, P = .989, fixed-effect model was adopted, test for overall effect: z = −1.977
