Comparison of gastric cancer-free survival rate in each group according to ABC method. a Patients were classified into two groups (A and others). The differences in cancer-free survival rates among the two groups were evaluated by Kaplan–Meier analysis (log-rank test). The differences between group A and others were not significant (P = 0.058). b Gastric cancer-free survival rate for the true A group and the other groups assessed using Kaplan–Meier analysis. Patients in group A were subclassified into the true A (without endoscopic atrophic gastritis) and pseudo A (with endoscopic atrophic gastritis) groups. The patients were classified into two groups (true A and others). The differences in cancer-free survival rates among the two groups were evaluated by Kaplan–Meier analysis (log-rank test). The differences between the true A group and the others group were significant (P = 0.017)
