a Number of comparisons.
b The crude OR and 95% CI were calculated based on the genotype frequencies.
c P value of Q-test for heterogeneity analysis.
d The genetic variant comparisons in Analysis 1 were TC versus TT, CC versus TT, TC/CC versus TT, CC versus TT/TC and C versus T for heterogenous, homogenous, dominant, recessive and additive model respectively.
e The genetic variant comparisons in Analysis 2 were TC versus CC, TT versus CC, TC/TT versus CC, TT versus CC/TC and T versus C for heterogenous, homogenous, dominant, recessive and additive model respectively.
