Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Biomarkers in the blood, a range of approximately 20 parameters, there will be a search for predicting factors on exacerbation frequency and mortality on the long term and for the effect of the lung rehabilitation on these biomarkers on the short term. The number of exacerbations will be recorded. | — |
Secondary
| Measure | Time frame |
|---|---|
| Investigating the number of exacerbations, hospitalisations, progression of COPD, mortality, health care use, quality of life over a long term follow-up period. Searching for correlations between biomarkers in blood and bonde density, muscle quality and peripheral vasculature quality. Studying the effects of rehabilitation program on muscle quality. | — |
