LOS: length of stay; NIHSS: National Institutes of Health Stroke Scale score; IQR: interquartile range; mRS: modified Rankin Scale score. Poor functional outcome is defined as discharge mRS >2. Unfavorable discharge disposition is defined as discharge to a facility other than home or inpatient rehabilitation.
