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

*<p>SG = superficial gastritis; CAG = chronic atrophic gastritis; IM = intestinal metaplasia; DYS = dysplasia; OR = odds ratio; CI = confidence interval.</p>†<p>Odds ratios and 95% confidence intervals were estimated in reference to SG/mild CAG group, and adjusted for age, gender, <i>H. pylori</i> infection, smoking and drinking status. The analysis was restricted to participants with complete data on all covariates.</p>‡<p>Six participants with missing values on rs2910164 genotype were excluded from analysis.</p>§<p><i>P</i> 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.</p>∥<p>Fifteen participants with missing values on rs895819 genotype were excluded from analysis.
