  • aStatistical significance tests of χ2 yielded P < 0.001.

  • bIncludes history of peptic ulcer.

  • cMucositis and disorders: other categories were combined due to small cell sizes (<11) for mucositis.

  • dEstablished conditions: combined count of those with peptic ulcer or gastric ulcer or duodenal ulcer or a history of gastritis, which are indicator conditions for H. pylori testing.

  • eFrequencies are of total number with an established condition.
