  1. *Values are only from 8 of the control subjects. The other 4 subjects were lung donors with no former history of lung disease. Three out of four had the age interval between 46 and 65 years old and one between 31–45 years old. One of them was a former smoker with a smoking history of 7.5 pack years. There was no other lung function characteristics available for these individuals.
  2. Only values from 5 patients. § Only values from 6 patients. m denotes that data is missing. Data is presented as mean (range).
