Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
Safety Analysis Set: participants were randomized and received at least 1 dose of study medication.

Reporting Groups
  Description
Stribild Stribild QD and placebo to match Atripla QHS were administered during the double-blind phase. Stribild QD was administered during the extension phase.
Atripla Atripla QHS and placebo to match Stribild QD were administered during the double blind phase. Stribild QD was administered during the extension phase.
