  1. a6MWT, Six-Minute Walk Test; TUG, Timed Up and Go Test. Time represents the average number of weeks since first assessment (ICU discharge or ward arrival). Variance components are available from the authors. Time represents the change over time from first assessment in both groups. A positive value represents an increased score (6MWT distance increase – improved function), negative values represent decreased scores (TUG time decrease – improved function). Quad time represents the rate of change between time points of measurement. Group × time represents the treatment effect in this analysis: the interaction between group and time. Compared to the control group, the intervention group 6MWT distance improved by an average of 2.95 m/wk. Group × quad time represents the interaction between rate of change and group. **Significant results.
