Bolded results are statistically significant at p<0.05. The weighted N per initial model varies due to missing data on outcome variables and predictor variables. The weighted N for each multivariable model includes only those cases with valid data on the outcome variable and all of the predictor variables included in the model. All models adjust for the outcome variable measured at baseline and for: date of the follow-up survey; number of days between baseline and follow-up survey; cumulative Target Audience Rating Points (antismoking television advertising) in the 3 months prior to the follow-up survey; change in cigarette costliness (based on month of the follow-up survey); sex; age; education; socioeconomic status and Heaviness of Smoking Index (measured at baseline). – Predictor variable not included in multivariable model due to non-significant (at p<0.05) association with outcome variable in initial model.
