Definition of abbreviations:
- FEV1 = forced expiratory volume in 1 second
- FIV1 = forced inspiratory volume in 1 second
- IC = inspiratory capacity (L)
- FIF50 = forced inspiratory flow at 50% of the vital capacity (L/s)
- PIF = peak inspiratory flow (L/s)
- ∆ = changes in initial values of lung function parameters when reaching the PD20 endpoint
- A higher VAS score denotes a higher degree of dyspnea
