  • Adjusted means based on 16 covariates including demographics, parenting, competence and personality. Higher levels of e-cigarette use are collapsed in cells for yearly/monthly use and weekly/daily use so as to increase power for pairwise comparisons. Cells with a common subscript do not differ significantly (p>0.05) in pairwise comparisons with Tukey-Kramer adjustment.

  • **** indicates p<0.0001.
