NO and FEV
% predicted of healthy controls and asthmatics. The scatter plots show the airway inflammation and lung function of healthy controls (n = 3) and untreated asthmatics (n = 12) as assessed by FEV1% predicted (A) and fractional exhaled nitric oxide (FENO) (B). Asthmatics had significantly increased airway inflammation and significantly decreased lung function, compared to healthy controls. The bars indicate the mean ± SEM. * = indicates p value < 0.05.
