Participant Flow

Subjects were recruited for study participation at the Laboratory of Clinical Psychopharmacology at The Scripps Research Institute in La Jolla, CA from 10/13/2014-11/6/2019. One Hundred three subjects were enrolled, One Hundred one subjects completed 1-week of medication/placebo, Ninety subjects completed 8-weeks of counseling, and Eighty-four subjects completed a 12-week follow up visit.

Seventy-one subjects were excluded prior to enrollment: sixty-seven did not meet admission criteria and four declined to participate.
