Final logistic regression model predicting cigarette smoking susceptibility (post-RSL) from experimental condition
| Predictor | b | SE | OR (95% CI) | Wald χ2 | p Value |
|---|---|---|---|---|---|
| Experimental condition* | |||||
| Hidden | −1.44 | 0.61 | 0.24 (0.07 to 0.78) | 5.59 | 0.02 |

| Cigarette smoking susceptibility (pre-RSL)† | 4.56 | 0.72 | 95.58 (23.57 to 391.51) | 40.28 | <0.01 |
*The reference category is the cashier condition (0).
†Participants with scores greater than ‘3’ on this measure were coded as ‘at risk’ of future smoking susceptibility (1).
