Figure 2.

Lung function parameters in patients chronically colonized with H. influenzae (yes) and in patients not chronically colonized with H. influenzae (no) as measured by (A) spirometry and (B) impulse oscillometry.

Notes: The graphs show levels of these parameters at stable phase (using the mean of each parameter at all stable visits). The data are presented as the median (interquartile range) and *P≤0.05 for comparison between colonized and non-colonized patients.

Abbreviations: H. influenzae, Haemophilus influenzae; %p, percent predicted; FEV₁, forced expiratory volume in 1 second; FVC, forced vital capacity.
