Univariate and multivariate predictors of poor outcome (90-day mRS=5-6 vs. mRS<5) based on baseline characteristics and dichotomized DWI and Tmax>8sec baseline lesion volumes

Variables	Univariate analysis with all patients	Multivariate analysis with all patients having technically adequate baseline DWI and PWI
	(N=174)	(N=161)
	p	p	OR(95%CI)
Age	<0.001	0.001	1.48(1.17-1.88)*
Systolic BP	0.070
Baseline NIHSS	<0.001	0.010	1.13(1.03-1.24)*
Time to treatment	0.049
Evidence of Obstruction on MRA1	0.004
Degree of obstruction MRA1	0.004
DWI baseline volume >80 mL	0.001
Tmax>8sec baseline volume >85 mL	<0.001	<0.001	8.9(2.9-27.5)

^*odds ratios (OR) are estimated for 5 years increase of age and 1 score increase of NIHSS.
