  1. * Significant difference in the prevalence of former and current chewers by Chi-square analysis (p < 0.05)
  2. † Significant difference by logistic regression model (P < 0.05).
  3. a May not total 100% due to rounding.
  4. b Odds ratios (OR) refer to the risk of former chewers versus current chewers according to each variable. OR > 1 indicates a higher likelihood of being a former chewer (quit chewing).
  5. c aOR: adjusted odds ratio for age (years), quids per day, ethnicity and alcohol consumption by logistic regression model; 95% CI: 95% confidence interval.
