Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Subjects were recruited from the HIV clinics at San Francisco General Hospital, Stanford University, Case Western Reserve University, and Rush University/CORE Center between September, 2008, and December, 2009.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
All 45 enrolled patients were assigned to study intervention. We over-enrolled by 3 subjects given 2 premature treatment discontinuations and one subject with unavailable baseline peripheral blood mononuclear cell (PBMC) samples available for analysis.
