Flow chart of studies identification and inclusion. A. Forest plot of gastric cancer (GC) risk with the TNF-α-308 GG genotype (overall). A random-effects model was used for calculation. B. Forest plot of GC risk with the TNF-α-308 GA genotype (overall). A random-effects model was used for calculation. C. Forest plot of GC risk with the TNF-α-308 AA genotype (overall). A fixed-effects model was used for calculation. D. Forest plot of GC risk with the TNF-α-308 GA + AA genotype (overall). A random-effects model was used for calculation.

A. Begg's funnel plot for publication bias test for TNF-α-308 GG polymorphism. No evidence of publication bias (P = 0.84). B. Begg's funnel plot for publication bias test for TNF-α-308 GA polymorphism. No evidence of publication bias (P = 1.0). C. Begg's funnel plot for publication bias test for TNF-α-308 AA polymorphism. No evidence of publication bias (P = 0.60). D. Begg's funnel plot for publication bias test for TNF-α-308 GA + AA polymorphism. No evidence of publication bias (P = 1.0).
