Participant Flow

Enrollment into this trial occurred between April 2011 and May 2012. Participants were recruited from the HIV outpatient clinics associated with the Indiana University Health medical system.

Thirty-two persons screened for enrollment. Two of these failed screening (both for having screening HIV-1 RNA levels \>50 copies/mL); the remaining 30 were equally randomized into the two study groups.

PRIMARY outcome

Timeframe: Baseline and 24 weeks

Population: In the Switch to tenofovir/emtricitabine plus raltegravir arm, two FMD measurements at 24 weeks were removed from the analysis due to poor quality imaging.

Change in FMD is a measure of change in endothelial function
