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

  Patients with H. pyloricultures (n = 469) Selected patients for p-CagA analysis (n = 146) pvalue*
Age (year [mean ± SD]) 48.1 ± 14.2 50.4 ± 16.3 NS
Gender (F/M) 264/205 73/73 NS
Endoscopic diagnosis (year; n(F/M))    
   Gastritis    
   - without intestinal metaplasia 44.3; 209 (137/72) 41.2; 31 (18/13) NS
   - with intestinal metaplasia 54.5; 39 (29/10) 57.0; 28 (22/6) NS
   Duodenal ulcer 48.0; 131 (68/63) 46.6; 31 (14/17) NS
   Gastric ulcer 51.3; 64 (17/47) 49.5; 32 (7/25) NS
   Gastric cancer 60.4; 26 (13/13) 60.6; 24 (12/12) NS
  1. * Either the age or the gender was matched between the 146 selected patients and the entire patients in each sampled groups (Pearson chi-square test for gender & Student's t test for age analysis).
