Sensitivity analysis for XPC Lys939Gln polymorphism and gastric cancer risk (dominant model Gln/Gln + Gln/Lys vs. Lys/lys). This figure shows the influence of individual studies on the summary OR. The middle vertical axis indicates the overall OR and the two vertical axes indicate its 95% CI. Every hollow round indicates the pooled OR when the left study is omitted in this meta-analysis. The two ends of every broken line represent the 95% CI.
