From: Decision curve analysis revisited: overall net benefit, relationships to ROC curve analysis, and application to case-control studies

Figure 3

Illustration of the net benefit achieved using an accurate binary diagnostic test. Dichotomising the complex example model with the optimal ROC cutoff probability based on the maximum Youden index (or Peirce's "science of the method") results in an arc-shaped decision curve, with respect to the net benefit for the treated (a), the net benefit for the untreated (b), or the overall net benefit (c).
