Fig 3 Intraoperative systolic blood pressure (SBP) in patients undergoing carotid endarterectomy (CEA) with regional anesthesia (RA) or general anesthesia (GA) at baseline (t0), after induction of anesthesia (t1), before cross-clamping (t2), after cross-clamping (t3), and 1 hour after admission to the postanesthesia care unit (t4). Data are presented as mean ± standard deviation. *P < .05, **P < .001; NS, Not significant.
