Table 1 The clinical characteristics between all patients with isolated H. pylori strains and the selected patients for analysis of the p-CagA intensity of the strains

From: Helicobacter pylori with stronger intensity of CagA phosphorylation lead to an increased risk of gastric intestinal metaplasia and cancer
