Figure 1. Flow of Patients Through the Study of Rehabiliation for Patients With Acute Respiratory Failure.

BMI indicates body mass index (calculated as weight in kilograms divided by height in meters squared); SRT, standardized rehabilitation therapy.

^aPatients could have more than 1 exclusion. Either patient or surrogate may have provided or refused consent.

^bOne patient after completing intervention was deemed technically ineligible; the patient was consented and randomized to SRT but was found to be unable to walk prior to study and included in the primary analysis.
