VR, variant; WT, wild-type; Ht, heterozygote; VR Ho, variant homozygote; WT Ho, wide-type homozygote.
The results were in bold, if the 95% CI excluded 1 or P<0.05; Ph, P value of Q-test for heterogeneity test, and Random effects model was used when P value for heterogeneity test <0.1; otherwise, fixed effects model was used in the analysis.
