HPE, Helicobacter pylori eradication; BMI, body mass index; Q1-4, quartile 1-4; SD, standard deviation.

Between-group P-value: categorical data, chi-square test (C) or Fisher exact test (F); continuous data, independent t test (T) or Wilcoxon rank-sum test (W); within-group P-value: paired t test (P) or Wilcoxon signed-rank test (S).
