Comparison of 90-day clinical outcomes in patients with 7-day NIHSS ≤6 compared to NIHSS ＞6

	7-day NIHSS ≤6	7-day NIHSS >6	X 2/z	p
Median mRS discharge (IQR)	1.00 (1.00, 2.00)	4.00 (4.00, 5.00)	−11.33	<0.001
90-Day favorable outcome, n (%)	98 (88.29)	19 (15.20)	125.63	<0.001
90-Day mortality, n (%)	4 (3.60)	32 (25.60)	22.01	<0.001

Favorable outcome: mRS (0–2) at 3 months. Poor outcome: mRS ≥3. Abbreviations: IQR, interquartile range; mRS, modified Rankin scale; NIHSS, National Institutes of Health Stroke Scale.
