  • a Factors included in multivariate analysis of favorable outcome: age, hta, previous stroke or TIA, systolic BP, admission NIHSS score and ASPECTS, prestroke mRS ≥1, intravenous rtPA, general anesthesia, delay in imaging-to-groin puncture, site of occlusion, and the Sofia catheter. Factors included in multivariate model of successful reperfusion: age, current smoking, admission ASPECTS, site of occlusion, intravenous rtPA, etiology, delay in onset to imaging. Factors included in multivariate analysis of excellent reperfusion: age, sex, current smoking, antiplatelet use, glycemia, admission ASPECTS, site of occlusion, intravenous rtPA, and the Sofia catheter. Factors included in multivariate analysis of first-pass effect: age, current smoking, previous stroke or TIA, antiplatelet use, glycemia, admission NIHSS score and ASPECTS, prestroke mRS ≥1, site of occlusion. and intravenous rtPA.
