Femoral artery plaque: A simple ultrasound clue for severe coronary stenosis

Figure 1 Two representations of the receiver operating characteristic curve showing the associations between femoral artery lesions (over 70% stenosis) as a binary variable and coronary artery disease severity (Gensini score) as a continuous variable in coronary heart disease patients. A: Sensitivity plotted against specificity at varying thresholds with accuracy at the intersection of the curves; B: Sensitivity plotted against 1-specificity at varying thresholds (conventional presentation).
