Notes: Performance status (PS), six-minute walk distance (6 MWT) in metres (m) and expressed as % predicted (from [21]), Sit-to-stand (STS) test expressed as seconds (s) and as a standard score (S-score) value calculated using age range-specific mean and standard deviations for healthy controls (from [22]): positive scores indicates STS S-scores above the mean. Pa: #Fisher’s exact (for counts) or unpaired t-test (for means) comparing baseline results for patients withdrawn and patients who completed study. Pb : #Fisher’s exact (for counts) or paired t-test (for means) comparing baseline and final test results for patients who completed the study.
