| Number of observations in intervals defined by ml ranges | Percentiles* of observations | ||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Average of ΔFEV1 | n | < -500 | -500, -50 | -50, 50 | 50, 150 | 150, 250 | 250, 500 | > 500 | Minimum | 5% | 25% | 50% | 75% | 95% | Maximum |
| Week 4-12 | 3313 | 24 | 623 | 695 | 717 | 563 | 554 | 137 | -1180 | -198 | -20 | 94 | 220 | 466 | 1966 |
| Week 4-24/26 | 2389 | 16 | 478 | 476 | 550 | 388 | 377 | 104 | -1148 | -203 | -30 | 88 | 214 | 474 | 1782 |

| On treatment | 3313 | 24 | 708 | 662 | 751 | 536 | 501 | 131 | -1180 | -213 | -32 | 82 | 208 | 467 | 1966 |
*For example, when averaging over time on treatment, the minimum average ΔFEV1 was -1180 ml and the maximum was 1966 ml; between these points, 5% observations were less than or equal to -213 ml and half were less than or equal to 82 ml; ΔFEV1, change from baseline in trough forced expiratory volume in 1 second.
