Values presented are count (percentage) for categorical and median (interquartile range) for ordinal and continuous variables. Proportion analysis tests for categorical variables were performed using the Fisher exact test. Nonparametric tests for ordinal and continuous variables were performed using the Mann–Whitney U test. CBF indicates cerebral blood flow/volume; CBV, cerebral blood volume; CTA, computed tomography angiography; FIV, final infarction volume; FIV/CBF, relative infarction growth; IVT, intravenous thrombolysis; mRS, modified Rankin Scale; MTT, mean transit time; NIHSS, National Institutes of Health Stroke Scale; Tmax, time to maximum; TTD, time to drain.
