FVC % predicted 0.3009 0.495 0.1941 0.59
FEV1 % predicted 0.1541 0.17036 0.01626 0.96
FEV1/FVC % -0.08721 -0.34021 -0.253 0.31
TLC % predicted -0.2773 0.2937 0.571 0.007
RV % predicted -0.1221 0.5781 0.7002 0.29

For each lung function parameter, the percent of change from baseline was used as dependent variable in the linear mixed-effects model. FVC = forced vital capacity; FEV1 = forced expiratory volume in one second; TLC = total lung capacity; RV = residual volume; PT = physical therapy.
