TNFSF15 and gastric adenocarcinoma: Logistic regression analysis (Table 4) showed that the subjects with TNFSF15 −358 CC genotype were at elevated risks for developing gastric adenocarcinoma compared with those with −358 TT genotype in the H. pylori infected group (OR 2.01, 95%CI, 1.65 to 4.25), but not in the H. pylori negative group (OR 0.87, 95% CI, 0.45 to 1.69).
