  • Smoking and hiatal hernia were analysed only for a subgroup.Helicobacter pylori was diagnosed histologically. “Carditis” is chronic inflammation in histologically verified gastric cardiac mucosa.

  • 1-150 p<0.05, **p<0.01, ***p<0.001 compared with non-IM group.

  • CI, confidence interval; NSAID, non-steroidal anti-inflammatory drug.
