Fig. 1From: Identification of Helicobacter pylori-related gastric cancer risk using serological gastritis markers and endoscopic findings: a large-scale retrospective cohort studyGastric cancer-free survival rate in each group according to ABC method. Patients in group A were subclassified into the true A (without endoscopic atrophic gastritis) and pseudo A (with endoscopic atrophic gastritis) groups. Patients were classified into five groups (true A, pseudo A, B, C, and D). The differences in cancer-free survival rates among the five groups were evaluated by Kaplan–Meier analysis (log-rank test). The differences between the true A group and the other four groups were not significant (P = 0.11)Back to article page
