*Numbers may not add to N=536 due to rounding off of weighted numbers.
†Adjusted for SES, daily consumption levels, recalled at least one anti-smoking advertisement, brand segment and previous quit attempts.
‡Also adjusted for covariates, and proportion of sample smoking from a plain pack each week of the interview.
**Due to skip error in questionnaire only asked of current smokers aged under 60 years.
SES, socioeconomic status.
