Table 2. Multivariate analysis of predictors of moderate-to-high clinical severity ^a.

Predictors	OR	95% CI	P
AR vs. AS	4.55	2.42-9.18	<0.001
Age (per unit increase)	1.22	1.11-1.39	0.026
Infarct volume (per unit increase)	1.17	1.10-1.33	0.009
Stroke etiology (lacunar subtype)	0.48	0.35-0.59	<0.001
FBG(per unit increase)	1.24	1.10-1.45	0.016
CRP(per unit increase)	1.35	1.20-1.77	0.018

^a Multivariable model included all of the following variables: age, gender, BMI, stroke syndrome, stroke etiology, vascular risk factors, acute and pre-stroke treatment, lesion volumes, and blood levels of WBC, Platelet, Total cholesterol, LDL cholesterol, CRP and FBG; moderate-to-high clinical severity is defined as NIHSS score >6.

OR, odds ratio; CI, confidence interval; FBG, fasting blood glucose; CRP, C-reactive protein; NIHSS, National Institutes of Health Stroke Scale; AR, aspirin-resistant; AS, aspirin-sensitive
