Table 1. Baseline characteristics, overall and by reperfusion success following BGC-assisted thrombectomy for stroke.
Values expressed as n (%) unless otherwise specified. Y indicated years; mTICI indicates modified treatment in cerebral ischemia score; IV-tPA indicates intravenous thrombolysis; NIHSS, National Institutes of Health Stroke Scale; min indicates minutes; MCA indicates middle cerebral artery; M1 indicated first MCA segment; M2, second MCA segment; M3, third MCA segment; ICA, internal carotid artery.
*p-values calculated using the student t-test or Aspin-Welch-Satterthwaite t-test and χ2 test or Fisher's exact test as appropriate.
