a: Baseline model adjusted for age, NIHSS score, ASPECT score, collateral circulation, reperfusion status, and TOAST classification
CCTC5-VR, cerebral circulation time from the vertical intracavernous portion of the internal carotid artery to the rolandic vein; mCCT, microvascular cerebral circulation time; TTPVR, time to peak of the rolandic vein.
