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 26 sites from 13 countries: 4 each from U.S. and South Africa; 3 from Brazil; 2 each from Peru, Botswana, Kenya, Malawi, and India; and 1 each from Haiti, Uganda, Zambia, Zimbabwe, and Thailand, between September 2006 and August 2009.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
HIV-infected persons at least 13 years of age, naive to antiretroviral therapy, who had received 1-14 cumulative days of a rifamycin-based TB regimen within 28 days prior to study entry, and had a CD4 count <250 cells/mm3. Randomization was stratified by screening CD4 (<50 vs =>50). Three participants were deemed ineligible and taken off study.

Reporting Groups
  Description
Immediate ART These participants initiated HIV antiretroviral therapy (ART) within 72 hours of randomization, which took place at most 2 weeks after initiating rifampin (RIF)- or other rifamycin-based TB treatment according to in-country national TB treatment guidelines. The study-provided drugs were efavirenz (EFV) 600 mg (provided to non-U.S. sites only; 1 tablet orally) and emtricitabine (FTC) 200 mg/tenofovir disoproxil fumarate (TDF) 300 mg (1 fixed-dose combination tablet orally) once daily. FTC 200 mg (1 capsule) and TDF 300 mg (1 tablet) could be substituted for the fixed-dose combination tablet and was provided by the study. Participants who could not tolerate EFV could be offered nevirapine (NVP) 200 mg daily for 14 days, then 200 mg twice daily. Substitutions with other locally-available U.S. Food and Drug Administration (FDA)-approved or tentatively approved antiretrovirals (ARVs) that were compatible with TB therapy could be used at the discretion of the site investigator.
Deferred ART These participants deferred ART until 8 to 12 weeks after initiation of their RIF- or other rifamycin-based TB treatment according to in-country national TB treatment guidelines. The study-provided drugs were EFV 600 mg (provided to non-U.S. sites only; 1 tablet orally) and FTC 200 mg/TDF 300 mg (1 fixed-dose combination tablet orally) once daily. FTC 200 mg (1 capsule) and TDF 300 mg (1 tablet) could be substituted for the fixed-dose combination tablet and was provided by the study. Participants who could not tolerate EFV could be offered NVP 200 mg daily for 14 days, then 200 mg twice daily. Substitutions with other locally-available U.S. FDA-approved or tentatively approved ARVs that were compatible with TB therapy could be used at the discretion of the site investigator.
