Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
HIV-infected pregnant women were recruited from antenatal clinics at DAIDS Clinical Trials Sites in Zimbabwe, South Africa, Uganda & Tanzania between May 14, 2008 & January 20th 2010. 1700 mother/infant pairs were enrolled & infants were given daily doses of Nevirapine for 6 weeks at which point there were randomized to placebo or extended NVP.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Infants were excluded from randomization if in first 42 days: had a positive HIV-1 DNA PCR, breastfeeding was discontinued, never initiated or permanently discontinued open-label NVP, certain graded abnormal labs, skin rash grade2B or higher, clinical hepatitis, serious illness/condition that prevented compliance, or use of rifampin/ketoconazole.
