Fig 1 A, Receiver operator characteristic curve for ICA peak systolic velocity to differentiate between ≥70% and <70% stenosis in the stented arteries. B, Receiver operator characteristic curve for ICA end diastolic velocity to differentiate between ≥70% and <70% stenosis in the stented arteries. C, Receiver operator characteristic curve for peak systolic velocity ratio of internal carotid artery and common carotid artery to differentiate between ≥70% and <70% stenosis in the stented arteries Journal of Vascular Surgery 2008 47, 74-80DOI: (10.1016/j.jvs.2007.09.031) Copyright © 2008 The Society for Vascular Surgery Terms and Conditions

Fig 2 The area under the ROC curve (area ± SE) and significance (P) were calculated for various ultrasound velocity values including PSV, EDV, and ICA/CCA ratio. Our analysis showed that EDV provided the best discriminative power.
