Figures in parentheses are percentages. Age, NIHSS, interval between onset time to imaging were presented by median and inter-quartile ranges. Others were presented patient numbers in each category. *p < 0.05 by Wilcoxon's signed rank test. NIHSS = National Institute of Health Stroke Scale, PAD = parent artery disease, SAD = small artery disease
