| Inflammatory BODE | BODE, inflammatory biomarkers, age, and hospitalisation history | [47] |
| ADO | Age, mMRC, FEV1 | [48] |
| DOSE | mMRC, FEV1, smoking status, exacerbation rate | [49] |
| CODEx | Comorbidity, obstruction, dyspnoea, and previous severe exacerbations | [50] |
BODE: body mass index, airflow obstruction, dyspnoea and exercise capacity index; BMI: body mass index (kg·m−2); FEV1: forced expiratory volume in 1 s (severity of airflow limitation, % predicted); mMRC: modified Medical Research Council dyspnoea score; 6MWD: 6-min walk distance; mBODE: modified BODE in which 6MWD is replaced by peak oxygen consumption; eBODE: exacerbations added to original BODE; BODEx: exacerbations replace 6MWD in the original BODE; inflammatory BODE: inflammatory markers added to original BODE; ADO: age, dyspnoea and airflow obstruction index; DOSE: dyspnoea, airflow obstruction, smoking status and exacerbations index; CODEx: comorbidities, airflow obstruction, dyspnoea and exacerbations index; peak V'O2: peak exercise oxygen consumption (mL·min−1).
