↵a Values are (No.) (%) unless otherwise indicated. Onset-to-groin puncture is defined as the interval between the onset of symptoms and the groin puncture; onset to imaging is defined as the interval between the onset of symptoms and the beginning of the first acquisition of MR imaging sequence; and onset to clot is defined as the interval between the onset of symptoms and the first contact of the mechanical thrombectomy device with the clot that occluded the vessel.
