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.
