Receiver operating characteristic curves showing the predictability of carotid artery FTc (A) and ΔVpeak (B) on hypotension after induction of anesthesia in elderly patients. The circles on the curves indicate the optimal cutoff values determined by maximizing the Youden index. AUC, area under the receiver operating characteristic curve
