Data are presented as mean (SD) or numbers of patients.
FEV1 = forced expiratory volume in one second; % ideal weight = weight as percentage of the predicted ideal weight; Pao 2= arterial oxygen tension; Paco 2 = arterial carbon dioxide tension.
↵1-150 p<0.01,
↵1-151 p<0.0001 for unpaired t test of mean of corresponding groups.
