  1. P values less than 0.05 were considered statistically significant
  2. Table shows the various endoscopy findings. Ninety four patients (40.3%) had normal endoscopy results. Significantly more patients with H. pylori positive had mucosal erosions in the stomach, and duodenum
  3. H. pylori Helicobacter pylori
  4. a%s may not add up to 100 as one patient be diagnosed with more than one endoscopic finding
