Figures & data

Figure 1 Estimated changes in FEV₁ by GOLD group and severe-exacerbation status.

Notes: The plot demonstrates that for each GOLD classification, those individuals with at least one severe exacerbation (dotted lines) had faster declines in FEV₁ on average compared with those who did not (solid lines). GOLD 0, no airway obstruction; GOLD 1, mild; GOLD 2, moderate; GOLD 3, severe; GOLD 4, very severe. Reprinted with permission of the American Thoracic Society.
