title: Efficacy of proton pump inhibitors for patients with duodenal ulcers: A pairwise and network meta-analysis of randomized controlled trials.
abstract: OBJECTIVE
  To compare the efficacy and tolerance of different proton pump inhibitors (PPIs) in different doses for patients with duodenal ulcers.
  
  
  METHODS
  An electronic database was searched to collect all randomized clinical trials (RCTs), and a pairwise and network meta-analysis were performed.
  
  
  RESULTS
  A total of 24 RCTs involving 6188 patients were included. The network meta-analysis showed that there were no significant differences for the 4-week healing rate of duodenal ulcer treated with different PPI regimens except pantoprazle 40 mg/d versus lansoprazole 15 mg/d [Relative risk (RR) = 3.57; 95% confidence interval (CI) = 1.36-10.31)] and lansoprazole 30 mg/d versus lansoprazole 15 mg/d (RR = 2.45; 95% CI = 1.01-6.14). In comparison with H2receptor antagonists (H2RA), pantoprazole 40 mg/d and lansoprazole 30 mg/d significantly increase the healing rate (RR = 2.96; 95% CI = 1.78-5.14 and RR = 2.04; 95% CI = 1.13-3.53, respectively). There was no significant difference for the rate of adverse events between different regimens, including H2RA for a duration of 4-week of follow up.
  
  
  CONCLUSIONS
  There was no significant difference for the efficacy and tolerance between the ordinary doses of different PPIs with the exception of lansoprazle 15 mg/d.
