Fig. 1 — Number of mistakes (a), of the intensity of perceived COPD symptoms (COPD Assessment Test, CAT Score) (b) and of the pulmonary obstruction (forced expiratory volume in 1 s, FEV1) (c) prior and after an 8-days intensive multimodal training. The number of mistakes (a) and the COPD symptom load (b) were strongly reduced by the training program. Conversely, FEV1 as an indicator of pulmonary obstruction (c) virtually remained unchanged. Data are presented as medians (large horizontal bars), 25th/75th percentiles (lower and upper edges of the squares), and minima and maxima (small horizontal bars)
