Values are presented as mean±standard deviation or number (%) unless otherwise indicated.
COPD: chronic obstructive pulmonary disease; MMRC scale: modified Medical Research Council dyspnea scale; SGRQ: St George's Respiratory Questionnaire; FEV1: forced expiratory volume in 1 second; FVC: forced vital capacity; V950: volume fraction (%) of the lung below -950 HU.
