Values are n (%) or mean (SD).
χ2 test (Fisher's exact for small cell sizes) or Student's t test for the entire patient cohort.
Additionally, we dichotomized the cohort into patients in which recanalization times were achieved in ≤60 min (‘Early recan’) and those in which recanalization times extended beyond 60 min (‘Delayed recan’).
