If not otherwise indicated, values are expressed as median (IQR). Mann–Whitney test was used for quantitative variables, Fisher’s exact test was used for qualitative variables. * 18 DLco missing. ** GK scoring > 2 points. Abbreviations: BMI = body mass index; FVC = forced vital capacity; DLco = diffusing capacity of the lung for carbon monoxide; GAP = gender, age, physiology; HR = high risk; IQR = interquartile range; LR = low risk; n = number; KL-6 = Krebs von den Lungen-6; y = years.
