∗ Helicobacter pylori eradication rate was 79.3% based on the intention-to-treat analysis. †Drinking fewer than 3 bottles/week, ‡drinking more than 3 bottles/week, and §taking less than 80% of all study drugs. The P value was derived from Student's t-test for age variable, and the P values for the other variables were derived from the chi-square or Fisher's exact test. SD: standard deviation.
