Multivariate (adjusted) predictors of increased hazard of >1 ED visit over 12-month Follow-upa
| Predictors | HR (95%CI) | P-value |
|---|---|---|
| Control vs intervention groupb | ||
| SHS exposure (NONE) | 1.85 (1.02, 3.38) | 0.04 |
| SHS exposure (YES exposed) | 0.82 (0.45, 1.51) | 0.53 |
| Allergic sensitization (positive vs negative) | 2.63 (1.37, 5.06) | 0.01 |
| SABA pre baseline (>4 vs <4 fills/12 months) | 1.52 (0.98, 2.34) | 0.06 |
| AMR pre baseline (<0.50 vs >0.50) | 0.64 (0.42, 0.99) | 0.05 |
| Age of children, (per each year increase) | 0.90 (0.82–0.98) | 0.01 |
a
Predictors were determined forward selection of variables in cox proportional hazards regression analyses based on level of significance in univariate analyses (all participants) and test of interaction where directional between group differences in HR were observed (Intervention status and SHS exposure).
b
Controlling for Allergen sensitization, SABA pre baseline, AMR pre baseline, age of children, interaction effect between group, and SHS exposure.
