|---|---|---|---|
| Airway data | |||
| Methacholine PD20 (µg) | 107 (28) | 597 (182)*† | 319 (97)* |
| Exhaled tidal nitric oxide (p.p.b.) | 8.2 (1.2) | 4.0 (0.4)* | 4.3 (0.9)* |
| FEV1 (% predicted) | 90 (2) | 100 (2)*† | 93 (2) |

| Systemic data | |||
| Overnight urinary cortisol/creatinine (nmol/mmol) | 6.14 (0.90) | 4.89 (1.04) | 4.79 (0.91) |
Values are expressed as means (SE) except methacholine PD20, nitric oxide and overnight urinary cortisol/creatinine which are geometric means (SE).
