Categories with empty OR, 95% CI and p value were the reference level in the model and p values were the reference level in the model.
EVT, endovascular therapy; IRF, Inpatient rehabilitation facility; IV-tPA, intravenous tissue-type plasminogen activator; LOS, length of stay; mRS, modified Rankin Scale; NIHSS, National Institutes of Health Stroke Scale; SNF, skilled nursing facility.
