Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Participants were recruited across 9 study sites (2 in Peru, one each in South Africa, Haiti, Uganda, Botswana, Zimbabwe, Brazil and Zambia) in the AIDS Clinical Trials Group system between April 2009 and September 2011.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Five hundred twenty nine subjects including participants and partners entered the study. Among the 529 subjects, 259 were participants, which included two participants with eligibility violations. Only the 257 eligible participants were included in the analyses. All participants started TDF/FTC +LPV/rtv and stratified by screening HIV-1 RNA only.

Reporting Groups
  Description
mDOT Arm Oral FTC/TDF+LPV/rtv or TDF+ZDV+LPV/rtv for 52 weeks. Modified directly observed therapy (mDOT) for the first 24 weeks and self-administration for the remaining 28 weeks.
Non-mDOT Arm Oral FTC/TDF+LPV/rtv or TDF+ZDV+LPV/rtv for 52 weeks. Self-administration of the study treatment (non-mDOT) for 52 weeks.
