↵a Univariate logistic regression analysis of patients undergoing endovascular therapy was performed with the following variables: ASPECTS (as scored on preprocedural head CT, 6–7 vs 8–10 and 6–8 vs 9–10), site of occlusion (M1 versus non-M1), onset to groin puncture, quality of recanalization (TICI scale), collateral grade, and clot length (>8 mm versus <8 mm).
