The situation is different in the net models. In the case of ideation, the significant ORs disappear entirely in the net model and no dose-response relationship can be seen in the set of ORs as a whole. In the case of plans, the significant OR associated with the highest category of involvement (3.0) is unchanged from the gross effects model. In the case of gestures, each OR associated with any of the smoking categories becomes elevated compared to the never-smoked comparison group in the net model. These ORs are in the range 1.7-2.0, but there is no dose-response relationship and none of these ORs is statistically significant. In light of this consistently elevated set of ORs, we might suspect that the association is genuine rather than due to random error. However, the pooled OR (95% CI in parentheses) of 1.8 (0.7–4.9) is not statistically significant in a model that makes a global contrast between respondents who ever smoked (i.e., pooling all the smoking categories) versus those who never smoked. In the case of attempts, finally, none of the ORs in
