^†Table shows percentages in each of the two ethnic groups (non-Latino whites and all Latinos) and in each of the two Latino subgroups, defined on the basis of language acculturation (low language acculturation and high language acculturation) for sociodemographic variables. (The continuous “age” variable presents group means and SD.) CI indicates confidence interval; and OR, odds ratio for history of nicotine replacement therapy use as a function of sociodemographic variables.

^*p < 0.05. Asterisks designate p value of subgroup difference within ethnic groups and acculturation groups, respectively.

^**p < 0.01.
