Major allele/minor allele.
Major homozygotes/heterozygotes/minor homozygotes.
Minor allele frequency (MAF).
ORs, 95% CIs and corresponding P values in an additive model were estimated using a logistic regression model.
Results in an additive model from GWAS and replication stages were combined by meta-analysis using a fixed-effect model under the absence of heterogeneity among studies for both loci (rs817826: P = 0.83, I2 = 0; rs103294: P = 0.53, I2 = 0).
