Categorical variables are shown as absolute numbers and percentages. Continuous variables are described by mean±SD or median and the first and third quartile (Q1, Q3). Good outcome is defined as mRS score at 90 days ≤2. Percentages are given for patients with the full availability of the investigated variable.
CVP, cardiovascular procedure; mRS, modified Rankin Scale; SAB, subarachnoid bleeding; sICH, symptomatic intracranial hemorrhage; TICI, Thrombolysis in Cerebral Infarction.
