Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Recruited at Pediatric AIDS Clinical Trials Group (PACTG) units in the U.S. and Puerto Rico, and Paediatric European Network for Treatment of AIDS (PENTA) units in Argentina, Austria, the Bahamas, Brazil, France, Germany, Italy, Romania, Spain, the United Kingdom and Ireland. Enrollment started 9/25/02 and ended 9/7/05.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Participants were stratified by age (<3 years versus 3+ years), origin (PACTG site or PENTA site), and exposure versus no exposure to antiretroviral therapy perinatally. 266 children were randomized, of whom 3 are excluded from all analyses (2 had consent withdrawn by parents after randomization, 1 was ineligible).

Reporting Groups
  Description
