Note. OR = odds ratio. CI = confidence interval. Initiation and Continuation columns represent parallel effects from the same model but recoding the phase of drinking. Phase was coded initiation = reference (0) for the Initiation column, and continuation = reference (0) for the Continuation column. Effect of primary interest in bold.
