Prevalence of H pylori associated ‘high risk gastritis’ for development of gastric cancer in patients with normal endoscopic findings

Figure 1 Prevalence of different phenotypes of gastritis in patients with H pylori infection in different age groups. With increasing age the number of patients with corpus-predominant gastritis increased significantly, whereas the antrum predominant gastritis decreased (Kruskal Wallis test; P < 0.01).
