The results in Table 3 show that the frequency distribution and logistic regression analysis of the rs2277438 polymorphism of TNFSF11 gene in gastric cancer and control group showed that the wild-type AA was used as the reference type, and the frequency distribution of AG heterozygous mutant type at rs2269700 was higher in the control group than that in the case group (43.76% > 41.19%). Here, TNFSF11 is linked to gastric cancer.
