Cost-Effectiveness of Rifaximin-α versus Lactulose for the Treatment of Recurrent Episodes of Overt Hepatic Encephalopathy: A Meta-Analysis

Figure 2

Meta-analysis of the cost-effectiveness of rifaximin-α plus lactulose compared with lactulose monotherapy in the second-line setting. A minimum of two studies are required to generate heterogeneity statistics (i.e. value or value); therefore, where only one study was available, these values could not be determined and were marked as not applicable (NA). Abbreviations: CI: confidence interval; DL: DerSimonian and Laird (random-effects model); : heterogeneity statistics; INB: incremental net benefit; IV: inverse variance; Lact: lactulose; : probability; Rif: rifaximin; US$: United States dollars.
