  1. Group I: patients with intemittent colonization with B. cepacia complex bacteria (1 or 2 isolates per year)
  2. Group II: patients with chronic colonization with B. cepacia complex bacteria (≥3 isolates per year)
  3. Group III: patients never colonized with B. cepacia complex bacteria
  4. FEV1 %: forced expiratory volume in 1 s % predicted
  5. FVC %: forced vital capacity % predicted
  6. BMI percentile: body mass index percentile
  7. p-value obtained by Wilcoxon test (level of significance: p-value < 0.05)
