Biomarker levels at time of exacerbation and at 4 weeks follow-up. a-f Levels of degradation fragments of collagens type III (serum C3M), IV (serum C4M), and VI (plasma C6M), elastin (serum ELM7 and EL-NE) and versican (plasma VCANM). g-i Levels of fragments released in relation to formation of collagen types III (serum Pro-C3), IV (serum P4NP 7S), and VI (plasma Pro-C6). Results are shown as geometric mean with 95 % confidence intervals. Biomarker levels at exacerbation and follow-up were compared using paired t-test. Significance levels: ***P <0.001, ****P <0.0001
