Table 1 displays patients’ demographic, stroke presentation and treatment findings of all 617 patients who underwent mechanical thrombectomy. Univariate logistic regression analysis between first pass- and non-first pass-reperfused patients is displayed on the very right column with corresponding p values.
*Data are No. (N) and frequencies (%), unless otherwise indicated.
†Reperfusion is defined as Thrombolysis in Cerebral Infarction 2b/3.
FP, first pass reperfusion; NIHSS, National Institutes of Health Stroke Scale; Non-FP, non-first pass reperfusion; IV tPA, intravenous tissue plasminogen activator.
