| FVC (l) | FVC = 0.0352 A + 0.068 H – 8.2668 | 0.84 | 0.71 | 0.293 |
| FEV1 (l) | FEV1 = 0.0405 A + 0.0854 H – 11.6318 | 0.87 | 0.76 | 0.321 |
| FEV1% (%) | FEV1% = –0.0586 A + 0.7216 H – 28.7192 | 0.57 | 0.32 | 0.323 |
| PEFR (l.min-1) | PEFR = –4.4409 A + 11.4414 H – 1138.4102 | 0.88 | 0.78 | 32.53 |
Abbreviation: A = Age, H = Body height, SEE = standard error of estimate.
