Figure 2:

Receiver operating characteristic (ROC) curve analysis evaluating occlusion length as a predictor of procedural and clinical outcomes in superficial femoral artery chronic total occlusions. (a) ROC curve demonstrating the predictive performance of occlusion length for successful lesion crossing. (b) ROC curve demonstrating the predictive performance of occlusion length for freedom from target lesion revascularization in the drug-coated balloon-alone group. The diagonal line represents the line of no discrimination.
