    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
