Risk association was tested using an additive genetic model for rs17588172 T>G but using a dominant genetic model for rs4236601 G>A due to the absence of minor-allele homozygote AA. The p values were calculated with adjustment for age, gender, and recruitment site. ^aConditional test p_con values were calculated with adjustment for rs4236601 or rs17588172 genotype as well as age, gender, and recruitment site. ^bIOP-adjusted test p_adj values were calculated with adjustment for IOP as well as age, gender, and recruitment site. Abbreviations: HTG, high-tension glaucoma; SNP, single nucleotide polymorphism; B, major allele; b, minor allele; CI, confidence interval; IOP, intraocular pressure.
