Definition of abbreviations: SD = standard deviation; FEV1 = forced expiratory volume in 1 second; DL_CO = diffusing capacity of the lung for carbon monoxide; BMI = body mass index; %CSA<5 = percentage of total lung area taken up by the cross sectional area of pulmonary vessels less than 5mm²; %LAA-950 = CT measurement of the percentage of low attenuation area less than −950 HU, defined as emphysema.
