[1] compared various multicomponent indices of chronic obstructive pulmonary disease (COPD) severity to see which best predicted survival and concluded ADO (age, dyspnoea and forced expiratory volume in 1 s (FEV1)) and BODE (body mass index, airflow obstruction, dyspnoea and exercise capacity) were the most valid. However, these were only the most valid of the indices they have considered. As committed researchers the authors should … ER -
