Logistic regression analysis for association of restrictions with 30 day smoking prevalence
| Odds ratio (95% CI) | P value | |
|---|---|---|
| Public place restrictions | 0.91 (0.83 to 0.99) | 0.03 |
| Total home ban | 0.79 (0.67 to 0.91) | <0.001 |
| Some home restrictions | 0.85 (0.74 to 0.95) | <0.01 |
| School ban | 0.99 (0.85 to 1.13) | 0.86 |
| Enforced school ban | 0.86 (0.77 to 0.94) | <0.001 |
2logL=16 271.0, (df=16), intracluster correlation=0.038, cluster variance=0.131, P<0.0001.
Odds ratios are adjusted for school grade, sex, race, adult smokers in home, and sibling smokers; n=14 746.
