The Bergen COPD Cohort Study (BergenKOLS)

The study started in 2006, and ended in 2014. More than 400 COPD patients and 300 healthy controls were included, and most were attempted followed until the end of 2014, with annual clinical examinations.

The main research question was to search for predictors of later advers outcomes such as mortality, exacerbation frequency, development of cachexia and lung function decline. Several papers are already published, and several more are underway.
