Flow diagram of study sample, HPTN 061*.

<p>*Men were categorized as previously diagnosed (prior HIV diagnosis) based on self-report or retrospective detection of antiretroviral drugs in samples from the enrollment visit (see Methods). The newly diagnosed group included three men who had acute HIV infection at enrollment.</p

Percent with sexually transmitted infections and self-reported risk behaviors by study visit and age group.

<p>Solid lines ≤30 years of age, dashed lines >30 years of age. Red squares: 2+ male partners; Blue triangles: Unprotected receptive anal intercourse with positive or unknown status male partners; Green circles: Sexually transmitted infections; Orange stars: HIV- positive male partners.</p
