Multivariate logistic regression analyses* with snus use versus non-use as the outcome in the three smoking categories; Never smoked, Previous smoker and Current smoker
* Only variables with significant odds ratios (ORs) with 95% confidence intervals (95% CI) are presented Significant ORs are marked in bold. The following variables were not included in the multivariate analyses due to non-significance in the univariate analyses: Unemployment, retirement
