  • Values represent aOR (95% CI) unless otherwise indicated. Bold values indicate the 95% CI does not include the null value.

  • aORs represent results of multivariable logistic regression analysis adjusted for all variables in the table.

  • *All respondents (n=12 987) included in analytic sample.

  • †Only HTP-aware respondents (n=4252) included in analytic sample.

  • ‡Only HTP ever users (n=697) included in analytic sample.

  • aOR, adjusted odds ratio; HTP, heated tobacco product; REF, reference value.
