Changes in clinical outcome measures from entry to end of year 3
| Elective | Symptomatic | Adjusted difference (95% CI)3-150 | p value | |
| FEV1 (% predicted) | –5.7 (2.6) | –8.1 (3.4) | 1.8 (–6.6 to 10.2) | 0.67 |
| FVC (% predicted) | –5.2 (2.3) | –6.3 (4.1) | 1.0 (–8.3 to 10.4) | 0.83 |
| Shwachman score | –4.3 (2.3) | –6.1 (2.1) | 1.7 (–4.7 to 8.1) | 0.59 |
| Chrispin-Norman score | –0.8 (0.8) | –1.0 (0.8) | 0.4 (–1.7 to 2.6) | 0.71 |
| Height (SD score) | –0.11 (0.13) | 0.05 (0.06) | –0.06 (–0.33 to 0.22) | 0.67 |
| Weight (SD score) | –0.06 (0.10) | 0.03 (0.09) | –0.10 (0.38 to 0.18) | 0.49 |
| Weight/height (% predicted) | 0 (1.5) | –0.8 (1.6) | 0.8 (–1.4 to 3.0) | 0.72 |
↵3-150 Adjusted for entry levels using an analysis of covariance. The signs are such that a positive value indicates that adjusted values are higher in the elective group at the end of year 3.
FEV1 = forced expiratory volume in one second; FVC = forced vital capacity.
