Genotype distribution and associations of genetic variants with risk of gastric lesions.

*SG = superficial gastritis; CAG = chronic atrophic gastritis; IM = intestinal metaplasia; DYS = dysplasia; OR = odds ratio; CI = confidence interval.†Odds ratios and 95% confidence intervals were estimated in reference to SG/mild CAG group, and adjusted for age, gender, H. pylori infection, smoking and drinking status. The analysis was restricted to participants with complete data on all covariates.‡Six participants with missing values on rs2910164 genotype were excluded from analysis.§P for trend were calculated by including the 3-level ordinal variable under codominant model for each polymorphism (0 = homozygote wild, 1 = heterozygote, 2 = homozygote variant) as a continuous variable to the multivariate models.∥Fifteen participants with missing values on rs895819 genotype were excluded from analysis.
