  • Note:—mTICI indicates modified Thrombolysis in Cerebral Infarction score; mAOL, modified Arterial Occlusive Lesion score; EVT, endovascular treatment.

  • b Reperfusion assessed as mTICI 2b–3 at end of EVT in the intervention group or as recanalization with mAOL score 2–3 on repeat CTA in the control group.
