Ceramide levels in BAL fluid from children and young people. Shown are levels of ceramide in BAL fluid collected during clinically indicated bronchoscopies from children and young people with cystic fibrosis (CF) and children who do not have CF but underwent a bronchoscopy for investigation of respiratory problems. Groups were matched for age (see Table E1). Individual data points are presented along with the mean (horizontal line) ± SD (error bars). An unpaired t test was used to determine significance. *P < 0.05.
