Definition of abbreviations: BMI = body mass index; CF = cystic fibrosis; FEF25–75% = forced expiratory flow between 25 and 75% of total lung volume.
Shown are the characteristics of patients whose flow–volume curves were used in the study. Shown are percentages for binary variables (sex, hospitalization), and means (standard deviation) for continuous variables.
