Some patients had two complications, so the total number of complications is higher than the number of patients who suffered any complication in each group.
mRS, modified Rankin Scale; NIHSS, National Institute of Health Stroke Scale; SICH, symptomatic intracranial hemorrhage; TICI, Thrombolysis in Cerebral Ischemia.
