  1. Baseline and 3-month data are presented as mean ± SD or n (%). Within-group-group differences are means ± SD. Between-group differences are presented as mean or odds ratio with 95% CI. CAT: COPD assessment test, higher values indicate greater impact of COPD; CRQ-SA: self-administrated chronic respiratory questionnaire, higher values indicate better health; Self-assessed PA and exercise: indicator questions according to the Swedish National Board of Health and Welfare, values of ≥11 correspond to ≥150 min of at least moderate PA/week; mMRC modified Medical Research Council dyspnoea scale, higher values indicate more dyspnoea; PA physical activity.
