From: Potential prognostic value of biomarkers in lavage, sputum and serum in a five year clinical follow-up of smokers with and without COPD

Figure 1

Change in pre-bronchodilator FEV 1 (L), FEV 1 (% pred.) and FEV 1 /FVC (left, middle, right) from 2006/2007 to 2012 in smokers with COPD (circles) and former healthy smokers (open squares). A larger drop below the line of identity indicates a larger decline in the respective lung function level. The changes with respect to GOLD category as listed in the text were done using post-bronchodilator values, which are slightly higher as compared to the pre-bronchodilator values displayed in this figure.
