Fig. 2From: Systematic review with network meta-analysis: dual therapy for high-risk bleeding peptic ulcersNetwork of the comparisons for the Bayesian network meta-analysis. Lines connect the interventions that were studied in head-to-head (direct) comparisons in the eligible controlled trials, while the interrupted lines connect indirect comparisons. The size of the nodes is proportional to the number of patients (in parentheses) to receive the treatment. The width of the lines was proportional to the number of trials (beside the line) comparing the connected treatmentsBack to article page
