  1. * Numbers shown are those who have been designated as smokers by the researchers based on the finding that they reported quitting smoking <28 days ago in the questionnaire. Numbers in brackets are the numbers of people for each category when categorised according to self-report of being a current smoker at the time of completing the questionnaire. NS: P value for Kappa statistic was not significant, indicating that agreement was not different from chance. NA: 95% CI not applicable as sample size too small.
