The genotypes of XRCC1 gene rs25487 polymorphism (P = 0.003) differed significantly between patients and controls, even after the Bonferroni correction (P < 0.05/5), and this polymorphism was significantly associated with gastric cancer after adjusting for age, sex, body mass index, smoking, drinking, especially under a dominant model (odds ratio or OR; 95 % confidence interval or CI; P 1.59; 1.20-2.00; 0.001).
