Weight loss v control for obese patients with asthma to improve lung function (% of predicted) at 1 year†
| Lung function tests | Mean change in weight loss group | Mean change in control group | Difference (95% CI) |
|---|---|---|---|
| †FVC=forced vital capacity; PEF=peak expiratory flow. | |||
| ‡Difference is not significant. | |||
| PEF (% of predicted) | 5.6 | −0.6 | 6.2 (−1.4 to 13.7)‡ |
| FEV1 (% of predicted) | 4.9 | −2.7 | 7.6 (1.5 to 13.8) |
| FVC (% of predicted) | 2.0 | −5.6 | 7.6 (3.5 to 11.8) |
