Pretransplant evolution of pulmonary function and functional exercise capacity following treatment with antifibrotic drugs. Forced Vital Capacity (FVC) (a), Total Lung Capacity (TLC) (b), Diffusion capacity (DLCO) (c) (all in (%predicted) and 6 min walk test (6MWT, meter) (d) at start of antifibrotic therapy (start) and at the moment of lung transplantation (LTx) in the included IPF patients. Dotted lines connect values in patients (n = 6/9) with a consecutive measurement at six months and just before transplantation; p-values (Wilcoxon signed rank test) are given for patients that had consecutive measurements
