Fig. 3

Graphical representation of the partial AUCs and the two-way partial AUC. a Partial AUC focusing on specificity (\(pAUC_{sp}\)), showing the area restricted to specificity values greater or equal to 0.6 (i.e., \(b_{sp} = 0.6\)). b Partial AUC focusing on sensitivity (\(pAUC_{se}\)), showing the area restricted to sensitivity values greater or equal to 0.75 (i.e., \(b_{se} = 0.75\)). c Simultaneous representation of both \(pAUC_{sp}\) and \(pAUC_{se}\). d Two-way partial AUC (tpAUC) as the intersection of \(pAUC_{sp}\) and \(pAUC_{se}\)
