Univariate and multivariate analyses of associations between <i>ERCC1</i> genotype, <i>ERCC2</i> genotypes, combined <i>ERCC1</i> and <i>ERCC2</i> variants and overall survival in gastric cancer patients.

*P values were calculated by Cox proportional hazards model using univariate analysis. **P values were adjusted for age, sex, race, smoking status, alcohol use, stage, histological grade, histological type and treatment in a Cox model. †The variant homozygous genotypes were ERCC1 rs3212986 TT, ERCC2 rs13181 GG and rs1799793 AA.
