Fig. 2From: Association between patient-reported outcomes and exercise test outcomes in patients with COPD before and after pulmonary rehabilitationLeft: Association between the SGRQ-C score (a), CAT score (b), CCQ score (c), and the 6MWD. Right: association between the change in SGRQ-C score (d), CAT score (e), CCQ score (f), and the change in 6MWD after PR. On the X-axis the MCID of 30 m for the 6MWT [42] is marked, on the Y-axis the MCIDs for SGRQ-C (−4.0), CAT (−2.0) and CCQ score (−0.4) are marked [10, 43].
