The indirect effect via TNFSF18 was at the margin of statistical significance (β indirect : 0.054, 95% CI: -0.006 to 0.115; OR: 1.06, 95% CI: 0.99-1.12; P = 0.077) and was estimated to account for 47.0% of the total causal effect, indicating a potential role for the GITR-GITRL signaling pathway in H. pylori -driven carcinogenesis.
Although the statistical evidence for this mediation pathway was at the margin of significance, its biological coherence and the substantial proportion of the total effect it potentially explains (47%) make it a compelling, hypothesis-generating finding that warrants further experimental investigation.
