Exercise assessment and CAT at admission and discharge of outpatient pulmonary rehabilitation.
| Assessment | Number of Patients | Admission Mean (SD) |
Discharge Mean (SD) |
Difference | MCID | p-Value |
|---|---|---|---|---|---|---|
| 6-MWT (m) | 44 | 472.8 (94.3) | 522.9 (91.5) | +50.2 (10.6%) | 61% | <0.001 |
| Wmax (W) | 43 | 100.9 (31.6) | 115.9 (32.5) | +14.6 (14.0%) | 66% | <0.001 |
| CWR70% (min) | 40 | 9.6 (7.4) | 14.0 (8.6) | +4.4 (45.8%) | 65% | <0.001 |
| CAT (score) | 24 | 14.6 (7.7) | 11.5 (7.5) | −3.1 (21.2%) | 71% | 0.001 |
MCID, ratio of patients who achieved the minimal clinical important difference; 6-MWT—6 min walking test, MCID = +30.5 m; Wmax—maximal workload on cycle ergometer, MCID = +6.8 W; CWR70%—constant work rate test at 70% of Wmax, MCID = +1.75 min; CAT—COPD Assessment Test, MCID = −2.
