^†Favorable outcome was estimated using multiple regression taking those variables into account: age, baseline NIHSS, baseline pc-ASPECTS, diabetes, successful recanalization, ASITN/SIR, first pass, puncture to recanalization time, distal occlusion.

^‡Successful recanalization was estimated taking those variables into account: age, baseline NIHSS, baseline pc-ASPECTS, hypertension, stroke of etiology, occlusion sites, first pass, stent retriever use, puncture to recanalization.
