This figure provides information on the study sample for assessment of eligibility (n = 5,359), the number excluded (n = 1,988) and randomized (n = 3,371), as well as the number allocated, followed up and analyzed for the experimental condition (n = 1,706) and control condition (n = 1,665).

Figure 3.
Percentage indicating intention to quit by education level.
This figure shows the percentages reporting intention to quit in the next 30 days (yes/no) by exposure to the control or experimental condition for each level of education (high school or less/some college/college or more). In adjusted regression models, the interaction for experimental condition by education was marginally significant at p = .057. The figure indicates a stronger effect for the pictorial condition versus the text-only condition among individuals with moderate education compared with higher educated groups.
