Enrollment and follow-up flow diagram for videogame intervention trial for sexual risk reduction. Note: Assessment refers to primary outcome assessment (delay of initiation of sexual intercourse);% is of active participants. Participants who did not initiate game play were still considered active and assessed for study outcomes. A total of six participants (four in PlayForward; two in control) who had initiated sexual intercourse (per primary outcome definition) at baseline were removed from the analysis of primary outcome.
