For TLR4 +896A/G polymorphism, individuals carrying the variant AG genotype had a significantly increased gastric cancer risk compared with the AA genotype (heterozygous model) (AG vs. AA: OR = 1.67, 95%CI = 1.39–2.01, P = 0.000) (Figure 2A). The gene discussed is TLR4; the disease is gastric cancer.
