Odds ratios are adjusted for baseline measures of ever cigar use, ever e-cigarette use, grade, gender, race/ethnicity (White, Hispanic, Other), and site (CHS, H&H, YASS).
Note: Bold font indicate statistically significant associations at p ≤ .05. CHS=Children’s Health Study; H&H = Happiness & Health Study; YASS=Yale Adolescent Survey Study; AOR = adjusted odds ratio; 95% CI = 95% confidence interval. The interaction between ever cigar use at baseline and site was not statistically significant (p=0.648).
