Recruitment Details
| Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations |
|---|
| Study participants were recruited at 10 study sites, 4 in South Africa and 1 each in Uganda, Zimbabwe, Zambia, Malawi, Tanzania and India between November 9, 2006 and March 19, 2010. |
Pre-Assignment Details
| Significant events and approaches for the overall study following participant enrollment, but prior to group assignment |
|---|
| Infants and children 6 - 36 months of age (lower age limit changed to 2 months in Protocol Version 4.0) were stratified by age (2-<6 months, 6-<12 months and >=12 months) and randomly assigned to receive either AZT/3TC/NVP or AZT/3TC/LPV/r. One subject was randomized but never started study treatment. |
