1.Primary Outcome
Title Percentage of Participants With Human Immunodeficiency Virus -1 Ribonucleic Acid (HIV-1 RNA) <50 Copies/mL
Hide Description Viral load (number of HIV-1 RNA copies in the blood) was measured at baseline and scheduled study visits. A decrease in viral load is a measure used to assess the effectiveness of antiviral treatments. The percentage of participants with HIV RNA less than 50 copies/mL at each time point is presented.

Certain Agreements
Principal Investigators are NOT employed by the organization sponsoring the study.
There IS an agreement between Principal Investigators and the Sponsor (or its agents) that restricts the PI's rights to discuss or publish trial results after the trial is completed.
Abbott requests that any investigator or institution that plans on presenting/publishing results disclosure, provide written notification of their request 60 days prior to their presentation/publication. Abbott requests that no presentation/publication will be instituted until 12 months after a study is completed, or after the first presentation/publication whichever occurs first. A delay may be proposed of a presentation/publication if Abbott needs to secure patent or proprietary protection.
