OR indicates odds ratio.

Multivariable models were adjusted for: age, insurance, medical history (atrial fibrillation/flutter, prior stroke or transient ischemic attack, coronary artery disease or prior myocardial infarction, carotid stenosis, diabetes, peripheral vascular disease, hypertension, dyslipidemia), on-hours arrival, ability to ambulate at admission, stroke diagnosis, and site characteristics (geographic region, rural vs urban, teaching hospital, number of beds).

Race and sex were significant predictors of each symptom type; race–sex interactions were not significant for weakness/paresis or other neurological symptoms (P>0.05), thus only main effects are shown for those symptom types.
