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

<p>NA: not available, OR: odds ratio, CI: confidence intervals. ^* GC location according to human stomach anatomy. ^† OR and 95% CI correspond to <i>TLR2</i>- 196 to -174del, <i>TLR4</i> Asp299Gly, <i>TLR4</i> Thr399Ile, <i>TLR4</i> rs11536889 or <i>CD14</i> -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.
