Regressions control for age group. Cl = confidence interval; COPD = chronic obstructive pulmonary disease; OR = odds ratio; TCA = Tobacco Control Act.
“Significant after adjustment for multiple comparisons.
Participants responded “no” or “not sure” (instead of “yes”) to the question, “Before today, had you heard about the specific smoking-related health effect described in the warning statement?”
Scale from 1 = “Not at all” to 7 = “Very much.”
“Not at all” or “A little” coded as 1 and “Somewhat” or “A lot” coded as 0.
