Table 2. Characteristics and outcomes by vessel of occlusion of the patients who were treated with endovascular thrombectomy. Age is presented as mean and standard deviation or median and interquartile range, as appropriate. ICA, internal carotid artery; IVT, intravenous thrombolysis administered; OTT, onset-to-treatment time to thrombectomy (presented as mean and standard deviation or median and interquartile range); M1 and M2, branches of the middle cerebral artery; MRS, modified Rankin scale (presented as median and interquartile range); NIHSS, National Institutes of Health Stroke Scale score (presented as mean and standard deviation)
