Figure 3 A forest plots for the incidence of metachronous gastric cancer between Helicobacter pylori-eradication group and non-eradication group in 22 studies combined with randomized control studies and cohort studies (A), 4 randomized control studies (B) and 18 cohort studies (C) in patients after endoscopic and operative resection. No heterogeneity in the total analysis (I² = 21%, P = 0.19), Randomized control studies (I² = 0%, P = 0.40) and cohort studies (I² = 28%, P = 0.13) was shown. A: Randomized control studies + Cohort studies; B: Randomized control studies; C: Cohort studies.
