Summary statistics for continuous variables are median and IQR. Associations between characteristics and type of stroke were evaluated by using Wilcoxon rank-sum test for continuous variables and Fisher’s exact test for categorical variables. Wald test was used for comparing mortality rates of two types of stroke.
*National Institutes of Health Stroke Scale.
†Skilled nursing facility (SNF) and long-term acute care facility (LTAC) values in parentheses without % are quartiles.
ED, emergency department; ICU, intensive care unit; LOS, length of stay; n/a, not available.
