For the purposes of this study data were collected from 21 207 current smokers. Using generalised estimating equations to control for multiple response sets multivariate models were tested to look for main effects of country and trends across time controlling for demographic variables. Results Knowledge remained low in all countries although UK smokers tended to be better informed. There was a small but significant improvement across time in the UK but mixed effects in the other three countries.
