- All values represent correlation coefficient (r).
- Missing data (--) indicate that there were no statistically significant relationships.
- FEV1 = forced expiratory volume in one second; RV = residual volume; TLC = total lung capacity; DLCO = carbon monoxide diffusing capacity; VA = alveolar volume R = resistance; X = reactance; LAA = low attenuation area; WA = wall area; SGRQ = St. George's Respiratory Questionnaire; MRC = Medical Research Council; HADS = Hospital Anxiety and Depression Scale
