Values presented are count (percentage) for categorical and median (interquartile range) for ordinal and continuous variables. AICA indicates anterior inferior cerebellar artery; CBF/CBV, cerebral blood flow/volume; CTA‐SI, CT angiography source images; FIV, final infarction volume; FIV/CBF, relative infarction growth; ICA, internal carotid artery; IVT, intravenous thrombolysis; mRS, modified Rankin Scale; MTT, mean transit time; NIHSS, National Institutes of Health Stroke Scale; pc‐ASPECTS, posterior circulation‐Alberta Stroke Program Early CT Score; PICA, posterior inferior cerebellar artery; SCA, superior cerebellar artery; Tmax, time to maximum; TTD, time to drain; VA, vertebral artery; WB‐CTP, whole brain CT perfusion.
Missing values: time from symptom onset, 22/60; IVT, 1/60; admission NIHSS, 11/60; premorbid mRS, 2/60; admission mRS (stroke severity in the emergency department), 4/60; discharge mRS 3/60; 90‐day mRS, 31/60.
