Data are presented as mean±sd unless otherwise stated
COPD: chronic obstructive pulmonary disease
FEV1: forced expiratory volume in one second
FVC: forced vital capacity
BMI: body mass index
#: one unit BMI is equivalent of height in metres squared, i.e., in a subject 170 cm high one unit change in BMI is equal to 3.89 kg
