  1. Number: number of patients who performed spirometry
  2. Group I: patients with intermittent colonization with B. cepacia complex bacteria (1 or 2 isolates per year)
  3. Group II: patients with chronic colonization with B. cepacia complex bacteria (≥3 isolates per year)
  4. Group III: patients never colonized with B. cepacia complex bacteria
  5. FEV1 %: forced expiratory volume in 1 s
