Arterial Elasticity: A Substudy of Strategic Timing of AntiRetroviral Treatment (START)
This is a substudy of the START study. It is planned to co-enroll at least 300 participants nationwide and 50 participants locally over 3 years at selected clinical sites. Clinical sites will represent a diverse study population across Asia, Australia, Europe, North America, and South America. Participants will be followed to the common closing date of the START study. This is estimated to be 6 years after the beginning of enrollment (3 years of enrollment and a minimum of 3 years follow-up for each participant). Before enrollment ends, sample size of the main START study will be re-assessed and sample size recalculated. At the same time, sample size for the Arterial Elasticity substudy will be recalculated.
