| Baseline, Mean (SD) |
Follow-Up, Mean (SD) |
Δ *, Mean (95% CI) |
p-Value | |
|---|---|---|---|---|
| SGRQ symptom score a | 40.4 (21.0) | 26.0 (21.1) | −14.4 (−18.4, −10.3) | p < 0.001 |
| SGRQ activity score b | 51.3 (25.4) | 39.1 (27.6) | −12.2 (−17.4, −7.0) | p < 0.001 |
| SGRQ impact score b | 27.2 (17.7) | 20.8 (18.5) | −6.5 (−10.2, −2.7) | p = 0.001 |
| SGRQ total score c | 37.3 (20.2) | 27.9 (20.2) | −9.4 (−13.3, −5.5) | p < 0.001 |
| EQ index value d | 0.758 (0.203) | 0.818 (0.168) | 0.060 (0.019, 0.102) | p = 0.005 |
| EQ VAS e | 59.1 (20.9) | 66.0 (20.3) | 6.9 (2.7, 11.1) | p = 0.002 |
a n = 69, b n = 57, c n = 51, d = 66, e = 67. SGRQ: lower scores mean better quality of life. EQ index value and EQ VAS: higher scores mean better quality of life. * Change from baseline.
