*The number of pack-years was calculated as the total number of years as a smoker multiplied by the average number of cigarettes smoked per day, divided by 20.
aChi-square test.
Results are mean values and based on the total population, unless stated otherwise.
FEV1 and ppoFEV1 are expressed as percentage of predicted values for age, gender and height.
FEV1 forced expiratory volume in one second, ppoFEV1 predicted postoperative FEV1, paO2 partial pressure of oxygen, paCO2 partial pressure of carbon dioxide.
