Univariate logistic regression analysis between first-pass- and non-firstpass-reperfused patients is displayed on the very right column with corresponding p-values. Values are displayed as absolute numbers and frequencies, mean ± SD or median and interquartile range (IQR).
*Data are No. and frequencies (%), unless otherwise indicated.
FP, first pass reperfusion; NIHSS, National Institutes of Health Stroke Scale; Non-FP, non-first pass reperfusion; TICI, Thrombolysis in Cerebral Infarction.;
