Mean differences (95% confidence intervals) between malnourished and normally nourished patients by age groups and by Pseudomonas aeruginosa colonisation

Age group (years)Vital capacity (% predicted)FEV1 (% predicted)mEF25 (% predicted)IgG (g/l)Po2 (kPa)
Example: In patients aged 6–11.9 years colonised with P aeruginosa, vital capacity was 11.3% of predicted lower in malnourished than in normally nourished children.
FEV1=forced expiratory volume in 1 second; Po2=oxygen tension; MEF25=mid expiratory flow at 25% of vital capacity.
