MCFS scores in groups defined according to BODE quartiles, CES-D scores and 6MWD
| BODE quartiles (Qs) | Depression | 6MWD | ||||||
| Q1 | Q2 | Q3 | Q4 | Not depressed | Depressed | 6MWD ⩾350 m | 6MWD <350 m | |
| Total fatigue score | 20.8 (12.2) | 24.7 (10.2) | 34.9 (9.7) | 39.4 (10.5) | 22.9 (12) | 40.9 (9.5) | 18.6 (11.9) | 31.5 (9.8) |
| Physical dimension | 8 (5.1) | 10.4 (4.5) | 14.2 (3.5) | 16.4 (2.9) | 9.1 (5.4) | 15.7 (3.3) | 7.4 (4.9) | 12.8 (4.2) |
| Cognitive dimension | 5 (3.3) | 5.5 (2.8) | 7.2 (2.9) | 8 (3.9) | 5.4 (3.3) | 9.7 (3.1) | 4.2 (3.1) | 7.1 (2.8) |
| Psychosocial dimension | 7.8 (4.9) | 8.8 (4.2) | 13.5 (4.2) | 15 (4.1) | 8.4 (4.8) | 15.5 (4.1) | 7.1 (4.9) | 11.6 (4.2) |
Mean values and SDs are shown.
All presented values have a p value <0.001 except for the difference of cognitive fatigue scores between BODE quartiles where p = 0.015
BODE, multidimensional index (B, body mass index; O, obstruction of airways as measured by forced expiratory volume in 1 s; D, dyspnoea as measured by the Medical Research Council scale; E, exercise capacity as measured by the 6MWD test); CES-D, Center for Epidemiologic Studies Depression scale; MCFS, Manchester chronic obstructive pulmonary disease fatigue scale; 6MWD, 6 minute walk distance.
