acOR, adjusted common OR (adjusted for age, history of diabetes mellitus, atrial fibrillation and previous stroke, presence of ICA-T occlusion, time from onset to randomization and baseline National Institute of Health Stroke Scale); cOR, common OR; GA, general anesthesia; ICA-T, internal carotid artery terminus; MAP, mean arterial pressure; ΔLMAP, difference between baseline and lowest MAP during GA; ΔMAP, difference between baseline and average MAP during GA.
