Participant Flow
Individuals were recruited to participate in the randomized controlled trial from social media via Meta, Grindr-a men-for-men geosocial networking app, and referrals from other studies conducted at the Center for AIDS Intervention Research beginning March 2024 with enrollment complete by July 2024. We iteratively refined ads in partnership with a youth advisory board and queer-led professional marketing firm to recruit a diverse sample of YSMM by race/ethnicity.
There is no difference between the number of participants enrolled in the study and the number who started the study.
