Figure 2 A: Forest plot of a meta-analysis of the association between H pylori and hepatocellular carcinoma risk (fixed-effects mode). It shows the ORs and 95% CI of each study, and the summary OR determined by meta-analysis. The proportion of total variation in study estimates, because of heterogeneity, was 44.0% (heterogeneity test statistics χ² = 14.28, on 8 df, P = 0.07, I² = 44.0%); B: Sensitivity-analysis: A Forest plot of a meta-analysis of the association between H pylori and hepatocellular carcinoma risk (random-effects mode).
