Utility of Saline-Induced Resting Full-Cycle Ratio Compared with Resting Full-Cycle Ratio and Fractional Flow Reserve

Figure 6

ROC curve analysis for the cutoff value of the sRFR to predict FFR <0.80 (AUC = 0.97; sensitivity: 90.6%; specificity: 98.2%; cutoff value of sRFR: 0.81). ROC, receiver operating characteristic; FFR, fractional flow reserve; sRFR, saline-induced resting full-cycle ratio; AUC, area under the curve.
