Funnel plots (not shown) and Eggeŕs regression tests showed that no publication bias existed in the following meta-analyses: 1) TLR2 -196 to -174del and risk of GC (t-value: 0.91, degrees of freedom (df): 3, P-value: 0.429), 2) TLR4 Thr399Ile and risk of GC (t-value: 2.00, df: 1, P-value: 0.294), and 3) TLR4 rs11536889 and risk of GC (t-value: 0.90, df: 1, P-value: 0.532). Here, TLR4 is linked to gastric cancer.
