CI = confidence interval; fSAD = functional small airways disease; TLC = total lung capacity; FEV1 = forced expiratory volume in 1 second; FVC = forced vital capacity; SGRQ = St. George’s Respiratory Questionnaire; 6MWD = six-minute walk distance; mMRC = modified Medical Research Council. Multivariable models were adjusted for age, sex, race, smoking status, smoking pack years, body-mass index (BMI), baseline postbronchodilator FEV1, and percent emphysema define as percent LAA < −950 Hounsfield units (HU).
