Fig. 2From: Diabetes does not impact the diagnostic performance of contrast-based fractional flow reserve: insights from the CONTRAST studyDiagnostic performance expressed by the area under the ROC curve for each metric in patients with or without diabetes. In patients with or without diabetes, contrast FFR (red line) has the largest area under the ROC curve, while iFR (blue line) and Pd/Pa (black line) have equivalent areasBack to article page
