Data presented as the mean (standard deviation) or frequencies and percentages as appropriate.
COPD, chronic obstructive pulmonary disease; DCLO, diffusing capacity of the lung for carbon monoxide; FEV1, forced expiratory volume-one second; PET SUVmax, maximum standardized uptake value on positron emission tomography. Data presented as mean ± SD or n (%) as appropriate. Continuous variables were compared using Mann-Whitney U test and categorical variables were tested using Chi-square test or Fisher exact test.
