A Cochrane review [Abstract] 1 included 6 studies with a total of 2 223 subjects. There were no statistically significant differences in rates of mortality, rebleeding or surgery between PPI and control treatment. Pooled mortality rates were 6.1% and 5.5% respectively (OR 1.12; 95% CI 0.72 to 1.73). Pooled rebleeding rates were 13.9% and 16.6% respectively (OR 0.81; 95%CI 0.61 to 1.09). Pooled rates for surgery were 9.9% and 10.2% respectively (OR 0.96 95% CI 0.68 to 1.35). PPI treatment compared to control significantly reduced the proportion of patients with stigmata of recent haemorrhage at index endoscopy; pooled rates were 37.2% and 46.5% respectively (OR 0.67; 95% CI 0.54 to 0.84). PPI treatment compared to control significantly reduced endoscopic therapy at index endoscopy; pooled rates were 8.6% and 11.7% respectively (OR 0.68; 95% CI 0.50 to 0.93).
Comment: The quality of evidence is downgraded by indirectness (differences in reported outcomes).
