Input: Seven studies with a total of 578 patients were included in the first comparison: mean percentage of rebleeding in H. pylori eradication therapy group was 2.9%, and in the non-eradication therapy group without subsequent long-term maintenance antisecretory therapy it was 20% (OR 0.17, 95% CI 0.10 to 0.32; there was no statistical evidence of heterogeneity; NNT was 7, 95% CI 5 to 11). Three studies with a total of 470 patients were included in the second comparison: mean percentage of rebleeding in H. pylori eradication therapy group was 1.6%, and in non-eradication therapy group with long-term maintenance antisecretory therapy it was 5.6% (OR 0.24, 95% CI 0.09 to 0.67; heterogeneity was not demonstrated; NNT was 20, 95% CI 12 to 100). Subgroup analyses were carried out to examine the effect of NSAIDS and of excluding H.pylori eradication failures from the analyses. Treatment of H. pylori infection is more effective than antisecretory non-eradication therapy (with or without long-term maintenance antisecretory therapy) in preventing recurrent bleeding from peptic ulcer. All patients with peptic ulcer bleeding should be tested for H. pylori infection, and eradication therapy should be prescribed to H. pylori-positive patients.
Output:

The review found that, for people who have had a bleeding peptic ulcer caused by Helicobacter pylori, treatment with antibiotics more effectively prevents gastrointestinal re-bleeding than acid-suppressing drugs. Antibiotics when Helicobacter pylori infection is present are also cheaper and more convenient than long-term acid-suppressing drugs.
