  • * Median and IQR as data were not normally distributed. Time between first test session and measurement of lung function and 6MWD was 7.7±5.5 and 2.4±3.0 months, respectively.

  • BMI, body mass index; FEV1, forced expiratory volume in 1 s; FVC, forced vital capacity; RV, residual volume; 6MWD, 6 minute walk distance.
