Figure 3.

Progression with age within 5 different types of colonization or infection respectively, depicted for each lung function parameter. Slopes were calculated from the fixed values predicted according to group using linear mixed-effect model analysis. (PA: chronically infected by P. aeruginosa; PA_comb: chronically infected by P. aeruginosa and other bacteria; SA: chronically infected only by S. aureus; intermit.: intermittently colonized by several bacteria; free: free from any bacterial colonisations).
