For students who had seen a cigarette pack in past 6 months, mean frequency of reading, attending to, thinking about and talking about health warnings and for students with smoking experience, the frequency of not having a cigarette or thinking about quitting in response to the warnings in 2011 and 2013, by smoking status (weighted data)

Responses measured on a five-point scale from 1 ‘never’ to 5 ‘every time I see them’.
In total, 104 students had missing data on the smoking status variable and were excluded from analyses. Missing data on the different items over the two surveys ranged from 37 to 131.
*Analyses adjusted for covariates of sex, age, school education sector, state and smoking status. CS, smoking in past week/established smokers; ES, experimental smokers; NSNS, non-susceptible never-smokers; SNS, susceptible never-smokers.
