Mean (SD) for 6MWD, Borg max and PWR. Median (interquartile range (IQR)) and median changes for ESWT and daily step count.
*Significant difference in change between groups.
ESWT, endurance shuttle walk test, Borg max, maximum Borg score at ESWT; 6MWD, 6-minute walking distance; N+R, non-invasive positive pressure ventilation (NIPPV) + rehabilitation group; R, rehabilitation group, Vo2max, maximal oxygen uptake at peak cycle exercise performance.
