Future risk determined by exacerbation history and degree of airflow limitation using the GOLD classification. GOLD 3 or 4 (severe/very severe) or a history of ≥2 exacerbations in the previous year confers 'high risk'. If both these indices are used to assess risk, the highest risk score is used.

First, we find that the new, multidimensional GOLD A–D classification provides better diagnostic separation as it identifies more individuals at high risk of exacerbations than a classification entirely based on the level of FEV 1.Second, we also find that survival is better in the more severe COPD group C (low lung function but less …
