TLR4 and Sepsis: In total analysis, the polymorphism rs4986790 of toll like receptor 4 gene showed no significant association with sepsis susceptibility under genetic models GG vs. AA (OR = 0.87, 95% CI = 0.53–1.43) (Fig. 2), GG + AG vs. AA (OR = 1.03, 95% CI = 0.83-1.29) (Fig. 3), GG vs. AA + AG (OR = 0.85, 95% CI = 0.52–1.41) (Fig. 4), allele G vs. allele A (OR = 1.03, 95% CI = 0.81–1.31) (Fig. 5) and AG vs. AA (OR = 1.05, 95% CI=0.83–1.33) (Fig. 6).
