A modest dose-response pattern can be seen in the aggregate predictions in two places in Table 2. First, the odds-ratio (OR) associated with lifetime dependence is somewhat higher than the OR associated with daily use, while the latter is somewhat higher than the OR associated with use. Second, early ages of use, daily use, and dependence are associated with somewhat higher risks than later onsets. However, neither of these patterns is statistically significant. Furthermore, contrary to expectation, current (at the time of the baseline interview) daily use and dependence are not associated with higher risk than past daily use and dependence. Similarly modest evidence for a dose-response pattern can be seen in the prediction of suicide plans. Even this modest pattern breaks down, though, in predicting gestures and attempts.
