- All values represent coefficient of determination (r2).
- Missing data (--) indicate that independent variables were not statistically significant.
- FEV1 = forced expiratory volume in one second; RV = residual volume; TLC = total lung capacity; R = resistance; X = reactance; LAA = low attenuation area; SGRQ = St. George's Respiratory Questionnaire; MRC = Medical Research Council
