Figure 1-S

Anthropometric characteristics of patients with pulmonary fibrosis (PF), cystic fibrosis (CF) and COPD on the waiting list and transplanted patients (assessed before transplantation): age (top panel), weight (left-middle panel), height (right-middle panel) and Body Mass Index (bottom panel). Data are expressed as mean (SE). NS, not significant.

Figure 2-S

Pulmonary function of patients with pulmonary fibrosis (PF), cystic fibrosis (CF) and COPD on the waiting list and transplanted patients (assessed before transplantation): forced vital capacity (FVC, top-left panel), FVC percentage of predicted values (top-right panel), forced expiratory volume in one second (FEV1, left-middle panel), FEV1 percentage of predicted values (right-middle panel) and FEV1/FVC (bottom panel). Data are expressed as mean (SE). NS, not significant.
