1. Fig. 1. Loess curve of association between brand-specific advertising exposure (adstock) and prevalence of brand consumption among underage drinkers ages 13–20. This figure shows the relationship between brand-specific advertising exposure (adstock) and the prevalence of youth alcohol brand consumption over the range of advertising exposure revealed through the survey. Adstock units represent a measure of cumulative exposure in the month a youth participant completed the survey and the preceding months, with an advertising half-life of one month. The loess curve uses a smoothing function to visually demonstrate the relationship between the two variables.
