  1. Abbreviations: CI confidence interval, e-cigarette Electronic cigarette
  2. aExposure, a binary variable (yes or no) was assessed at baseline by showing respondents an e-cigarette advertisement selected randomly from 5 popular TV and online advertisements and asking if they were aware of it
  3. bReceptivity was computed as an average of six items, each item self-rated on a scale from 1 (strongly disagree) to 5 (strongly agree) describing the perceived effectiveness of the advertisement shown to the respondent. The six items measured in relation to the advertisement’s effectiveness were “worth remembering,” “grabbed my attention,” “powerful,” “informative,” “meaningful,” or “convincing.” Responses were averaged for each ad and then across advertisements to obtain a single value for a respondents’ overall receptivity of the e-cigarette advertisements
  4. cCurrent e-cigarette users at follow-up were defined as persons who reported using e-cigarettes some days or every day
