The comparison of Δage in groups with a different disease prognosis. In Group A (CAG improved), the majority of subjects were Δage ≤0 (Stomach Age of these patients will be younger than their real age) on the contrary, the majority of subjects in Group C (worsened CAG) were Δage >0 (Stomach Age greater than their real age). And no significant difference in the subjects composition of Stomach Age in Group B (no change). In multiple comparisons, there was a significant difference between the three groups (P < 0.01), and the significant difference also existed between each group (P < 0.01).
