  1. *Values are only from five of the control subjects. The other four subjects were lung donors with no former history of lung disease. Of the lung donors, three out of four had the age interval 46-65 years old and one between 31-45 years old and one of them was an ex-smoker with 7.5 pack years. There were no other lung function parameters available for these individuals. §Values from three patients. Data is presented as mean (range).
