Registered outcomes4

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryCocaine Use as Assessed by Proportion of Visits (Excluding Excused Absences) With Cocaine-negative Urine Drug Screen4 weeksUrine is assessed for levels of the cocaine metabolite benzoylecgonine (BE), and the drug screen is considered positive for cocaine use if BE level is ≥ 150 ng/mL.
PrimaryCocaine Use as Assessed by Proportion of Visits (Excluding Excused Absences) With Cocaine-negative Urine Drug Screen12 WeeksUrine is assessed for levels of the cocaine metabolite benzoylecgonine (BE), and the drug screen is considered positive for cocaine use if BE level is ≥ 150 ng/mL.
SecondaryCocaine Use as Indicated by Proportion of Days of no Cocaine Use as Assessed by Timeline Follow-back4 weeksTimeline Followback (TLFB) is a method to assess of cocaine use that involves asking study participants to self-report their cocaine use over the past week.
