  1. aParameter estimates and 95% confidence intervals derived from univariate general linear (NIHSS score), ordinal (mRS distributions), or binary (dichotomized mRS score) regression models; the reference category is formed by patients with CAD. b Unadjusted models c No parameter estimate derived from from Mann-Whitney test. d Analysis adjusted for age, gender, pre-stroke modified Rankin scale score, medical history, prior medication, Alberta Stroke Program Early CT Score, and location of occluded vessel. CAD stands for cervical artery dissection; IQR, interquartile range; mRS, modified Rankin scale; NIHSS, National Institutes of Health Stroke Scale
