Adjusted for age, atrial fibrillation, hypertension, anticoagulant, fast glucose, occlusion sites (BA and VA+PCA), Pc-ASPECTS, onset to recanalization, aspiration, stent angioplasty, balloon angioplasty, and IA and/or IV tirofiban. ICH: intracranial hemorrhage; mRS: modified Rankin Score; mTICI: modified Tissue Thrombolysis in Cerebral Ischemia; OR: odds ratio.
