Physiological measures in children with asthma (n = 15)
| Baseline | Four weeks | Median change | p value | |
|---|---|---|---|---|
| FEV1 (% predicted) | 72.0 | 85.0 | 11 | NS |
| (60.5–81.5) (2) | (73.5–93.3) (5) | (−4.5–24.8) | ||
| FEF25–75 (% predicted) | 56.0 | 71.0 | 6.5 | NS |
| (45.0–67.5) (2) | (56.5–77.8) (5) | (−4.8–24.8) | ||
| PEFR (% predicted) | 81.3 | 87.8 | 8 | < 0.05 |
| (62.3–95.8) (3) | (70.5–101.9) | (3–13) | ||
| PEFR variability (%) | 12.5 | 7.8 | −4.0 | < 0.05 |
| (7.0 and 22.7) (4) | (5.7–9.1) (5) | (−11.1–1.2) |
Results are expressed as median (interquartile range) (any missing values).
FEV1, forced expiratory volume in one minute; FEF25–75, forced expiratory flow from 25% to 75% of lung volume; PEFR, peak expiratory flow rate; PEFR variability, variations of PEFR between morning and evening.
