Multivariate analysis of risk factors for acute stroke in patients with unilateral high-grade cervical internal carotid stenosis or occlusion.

CI, confidence interval; DM, diabetes mellitus; no., number; OR, odds ratio; ROAF, reversed ophthalmic artery flow.
Model 1: Statistically significant difference determined using multivariate logistic regression with forward selection model controlled for age, gender, vascular risk factors, and cervical stenosis but not including the variable of intracranial stenosis.
Model 2: Statistically significant difference determined using multivariate logistic regression with forward selection model controlled for age, gender, vascular risk factors, cervical stenosis, and ophthalmic artery flow direction.
