Table 4.
Summary of eight GEE analyses among respondents who smoked at the previous wave in which income level and wave are used as predictors of (1) quit attempts, (2) use of behavioral counseling, (3) use of cessation medications, (4) quit success, and awareness of (5) the reimbursement policy, (6) the campaign, (7) advertisements for cessation medications, and (8) other media attention about the reimbursement policy.
| 1. Quit attempt (n = 845) OR† (95% CI) |
2. Use of behavioral counseling (n = 845) OR (95% CI) |
3. Use of cessation medications (n = 845) OR (95% CI) |
4. Quit success (n = 845) OR (95% CI) |
5. Awareness of reimbursement possibilities (n = 845) OR (95% CI) |
6. Awareness of the campaign about the reimbursement policya (n = 845) Beta (95% CI) |
7. Awareness of advertisements for cessation medications (n = 845) Beta (95% CI) |
8. Awareness of (other) media attention about the reimbursement policy (n = 844) Beta (95% CI) |

All GEE coefficients are adjusted for gender, age group, and heaviness of smoking.
To adjust for multiple comparisons, estimates are considered significant when the p-value is below 0.004.
Questions about awareness of the campaign were only asked directly after the campaign ran, in wave 5. Therefore, ‘wave’ is not used as a predictor in this GEE analysis.
