Presenting results of probabilistic sensitivity analysis: the incremental benefit curve
提出增量效益曲线作为概率敏感性分析结果的呈现方式，展示给定支付意愿下各干预措施的增量净效益分布，帮助决策者了解非最优干预的福利损失，是对可接受曲线的补充。
Cost-effectiveness acceptability curves have become a common way of presenting the results of probabilistic sensitivity analysis. However, these curves do not provide information on what the loss of welfare or net benefit (NB) is for cases where a given intervention is not the optimal one. We describe an alternate approach to presenting the results of probabilistic sensitivity analysis called the incremental benefit curve that presents the entire distribution of incremental NB of each intervention for a given WTP value. The incremental benefit curve provides the decision maker information regarding the potential welfare loss with a given intervention for scenarios in which it is not the optimal intervention, and thus would be a useful complement to the acceptability curve.
