TLR2 and Sepsis: The combined results of the overall comparison indicated that there were significant associations between the TLR2 Arg753Gln polymorphism and sepsis risk under the allele comparison model and the dominant model, respectively (for A vs. G, OR 1.76, 95 % CI 1.05–2.95, P = 0.03; for AA/GA vs. GG, OR 1.92, 95 % CI 1.11–3.32, P = 0.02) (Table 2, Figs. 2 and 3).
