Chemoprevention of gastric cancer development after Helicobacter pylori eradication therapy in an East Asian population: Meta-analysis

Figure 2 A forest plots for the incidence of gastric cancer between Helicobacter pylori-eradication group and non-eradication group in 16 studies combined with randomized control studies and cohort studies (A), 4 randomized control studies (B) and 12 cohort studies (C) in non-gastric cancer patients with atrophic gastritis. There was no heterogeneity in the total analysis (I² = 30%, P = 0.13), randomized control studies (I² = 17%, P = 0.31) and cohort studies (I² = 18%, P = 0.26). A: Randomized control studies + Cohort studies; B: Randomized control studies; C: Cohort studies.
