25ConclusioniATV/r, RAL, and DRV/r were equivalent for virologic efficacyATV/r was less well tolerated than DRV/r or RALLargely due to cosmetic hyperbilirubinemiaRAL was superior to both PI/r regimens for combined tolerability and virologic efficacyDRV/r was superior to ATV/rVF with resistance was rareMore frequently observed with RALAnalyses are ongoing to evaluate:Cardiovascular, metabolic, skeletal, fat, inflammatory biomarkers, behavior, adherence, and key subgroup differences
