  1. A two-side P value less than 0.05 was considered significant and was given in bold
  2. CTP indicates computed tomography perfusion; NIHSS, National Institutes of Health Stroke Scale; IQR, interquartile range; tPA, tissue plasminogen activator; EVT, endovascular treatment; MCA, middle cerebral artery; ICA, internal carotid artery
