Individual studies included in the meta-analysis of TLR2, TLR4 and CD14 polymorphisms and gastric cancer.

NA: not available, OR: odds ratio, CI: confidence intervals. * GC location according to human stomach anatomy. † OR and 95% CI correspond to TLR2- 196 to -174del, TLR4 Asp299Gly, TLR4 Thr399Ile, TLR4 rs11536889 or CD14 -260 C/T allele analysis. ‡ This polymorphism was genotyped only in 69 gastric cancer patients and 212 functional dyspepsia controls. £ 539 subjects were excluded from the control group since they presented atrophic gastritis. § Non-cancer patients (individuals with normal gastric appearance, gastritis, gastric ulcers and peptic ulcers) and healthy individuals were included in the control group. ¶ The study population is from Poland. Δ The study population is from the United States. ¥ Twenty three individuals were excluded from the initial control group (N = 259) since they had atrophic gastritis and intestinal metaplasia. ¤ This polymorphism was genotyped only in 68 gastric cancer patients and 203 functional dyspepsia controls. ≠ 536 subjects were excluded from the control group since they presented atrophic gastritis.
