TLR4 and cancer: Furthermore, we also conducted a sensitivity analysis on the TLR2 and TLR4 polymorphism and risk of cancer by excluding all four studies departure from HWE among controls [20], [35], [40], [42] and their exclusion did not substantially affect the results of the meta-analysis (dominant model: OR = 1.68, 95% CI: 1.00–2.81 for −196 to −174del; dominant model: OR = 1.20, 95% CI: 1.00–1.44 for rs4986790; dominant model: OR = 1.49, 95% CI: 1.21–1.83 for rs4986791).
