Loss of skin elasticity is associated with greater impairment in lung function and increased pulmonary emphysema. Skin elasticity was associated with pulmonary emphysema determined by %LAA and Hist15. Skin elasticity was not associated with impairment in FEV1, however a significant association was observed between quartiles of skin elasticity and the severity of airflow obstruction, diffusion impairment, lung hyperinflation (RV/TLC) and pulmonary emphysema. Legend: FEV1, forced expiratory volume in 1 s; FVC, forced vital capacity in 1 s; DLCO, diffusion capacity for carbon monoxide; LAA% = low attenuation areas, lung voxels with Hounsfield Unit (HU) values less than −950; Perc15, HU value at the 15th percentile of the HU value histogram of lung voxels
