Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
368 participants were enrolled at multiple centers in different countries.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
368 participants were randomly assigned to 4 treatment groups (TMC278 25 mg: 93; TMC278 75 mg: 95; TMC278 150 mg: 91; and Efavirenz: 89). Participant flow through Week 240 was reported for the combined TMC278 and Efavirenz groups, as all TMC278 participants were switched after Week 96 initially to 75 mg and subsequently to 25 mg dose.

Reporting Groups
  Description
All TMC278 TMC278 25 mg, 75 mg, and 150 mg once daily
Efavirenz Efavirenz 600 mg once daily
