  • Data are n (%) or median (IQR).

  • *Study days are defined as the number of days between enrolment and the date the participant was recorded as being ready for discharge from ICU; if unavailable, the actual date of ICU discharge was used.

  • †Treatment days are defined as the number of days when the participant received physical rehabilitation on ICU; physical rehabilitation in either arm was only delivered Monday to Friday. Data are ‘median of means’, that is, a mean time was calculated for each participant and then, as the data were not normally distributed, a median (IQR) was calculated for each trial arm.

  • ICU, intensive care unit.
