Stethographics analysis was performed using the 16-channel lung sound analyzer system STG1602 (Stethographics, Boston, MA, USA) following the supplier's recommendations. Lung sound data are obtained from an intermediate deeper-than-normal breath (pattern 2; P2). Each breath pattern is recorded for a minimum of 30 seconds allowing 3 to 6 breaths to be taken, with measurements completed over 3 to 4 minutes. Each of the 16 parameters derived from one measurement are evaluated and a score from 0 to 10 is assigned based on the value of the individual parameter. The total standard Acoustic COPD Score (ACOPDS) is calculated as the sum of the individual score for each parameter, which permits a maximum score of 160. Although this stethographics analysis system was considered experimental, a higher score was associated with poor health outcomes and a lower score with a better health state.

The MMRC scale uses a simple grading system to assess a subject's level of dyspnea (shortness of breath). Subjects were asked to grade the degree of breathlessness related to activities by choosing 1 of the following answers: * 0: Not troubles by breathlessness except on strenuous exercise * 1: Short of breath when hurrying or walking up a slight hill * 2: Walks slower than contemporaries on the level because of breathlessness, or has to stop for breath when walking at own pace * 3: Stops for breath after about 100 meters or after a few minutes on the level * 4: Too breathless to leave the house, or breathless when dressing or undressing.

The BODE Index is a 10-point scale to assess prognostic factors in COPD patients. Body mass index ("B"), airway obstruction ("O"), dyspnea ("D"), and exercise tolerance ("E") are each graded on a 4 point scale (0 to 3), except body mass index (0 or 1) . The final BODE Index value is the sum of the scores for each prognostic factor, where a higher BODE score indicates a higher risk of death. The modified BODE (mBODE) index as defined by Lopez-Campos (2010) was used in this study, and is composed of the following factors: * Body mass index: (0 or 1) * Degree of airflow obstruction (FEV1% Pred): (0 to 3) * Functional dyspnea (MMRC Dyspnoea Scale): (0 to 3) * Exercise capacity (VO2max): (0 to 3) Lopez-Campos, José Luis, et al.

CT scans were assessed by two radiologists. A scoring system from 0 to 4 was applied, depending upon the component: 1. Extent of disease (emphysema): 0=absent, 1=mild, 2=moderate, 3=severe, 4=very severe 2. Severity of bronchial dilatation: 0=none; 1=mild (1.5x to 2.5x diameter of pulmonary artery); 2=severe (\>2.5x diameter of pulmonary artery) 3. Traction bronchiectasis: 0=none; 1=mild (1.5x to 2.5x diameter); 2=severe (\>2.5x diameter). 4. Total bronchiectasis score derived by adding the bronchial dilatation and traction bronchiectasis scores 5. Bronchial wall thickening: 0=none; 1=0.5x; 2=0.5-1x; 3= \>1x the diameter of the adjacent pulmonary artery 6. Small airways disease: 0=absent, 1=mild, 2=moderate, 3=severe and 4=very severe The total score (higher score indicated a poor outcome) was derived from the mean of all scores. This is described in Chaudhary, Nveed, et al. "Physiological and biological characterization of smokers with and without COPD." F1000Research 6 (2017).
