Successes: Over 80% of participants returned an at-home
HIV test Biological outcome = estimated HIV
incidence
90% of participants retained at first follow-up High retention (>70%) = can assess
outcomes Difference in retention by race/ethnicity =
different methods for data collection
Next step: Design an Intervention!
