Height as a predictor of lung function parameters for girls and boys given as the results of the crude linear regression analyses Y = β0 + β1h where h = height (cm) and Y = one of the lung volume measures (FEV0.5, FEV1, FVC and PEF). Slope β1 represents the change per cm height
| Lung volume measure | Intercept β0 | Slope β1 (SE) | SD | R2 |
|---|---|---|---|---|
| FEV1, FEV0.5=forced expiratory volume in 1 or 0.5 seconds; FVC=forced vital capacity; PEF=peak expiratory flow. | ||||
