| Outcome† | Crude odds ratio (95% CI) | p value | Adjusted* odds ratio (95% CI) | p value |
|---|---|---|---|---|
| *Adjusted for age, race, sex, clinic, Tanner stage, and parental smoking. | ||||
| †Outcomes based on occurrences over past year, except steroid days (past 6 months) and cough/wheeze (monthly average over the past 6 months). The outcomes were dichotomised at the following levels: school absences (⩽5 v> 5), ER visits and hospital admissions (none v any), visits to doctor (⩽6 v >6), days on steroids (⩽7 v >7), physical education restriction (none v any), and cough/wheeze (⩽1 v >1). | ||||
