Adjusted for age, sex, stroke type, Charlson Comorbidity Index, prestroke modified Rankin Scale, onset to admission intervals, length of stay, motor subscales of the FIM on admission, and cognitive subscales of the FIM on admission. CI: confidence intervals; FIM: functional independence measure; SE: standard error.
