The H. pylori density, inflammation and atrophy by gastric histology among the 146 patients infected with H. pylori isolates with different p-CagA intensity. The isolates with stronger p-CagA intensity were significantly associated with more severe acute inflammation (p = 0.01) and chronic inflammation (p = 0.005) but not with H. pylori density or gastric atrophy (p = NS) (Pearson chi-square test).
