In both patient groups, stroke severity was estimated with the National Institute of Health Stroke Scale (NIHSS), and stroke outcome was assessed by the modified Rankin score (mRS). When AIS patients with COVID-19 were compared to non-COVID-19 patients:
COVID-19 patients had more severe strokes (median NIHSS score of 10 vs. 6, respectively); COVID-19 patients had higher risk for severe disability following stroke (median mRS score 4 vs. 2, respectively); and COVID-19 patients were more likely to die of AIS
