aCI: confidence Interval
bSD: standard deviation
cOdds ratio interpreted as odds of agreeing to follow-up every 10 year increase in age
dDenotes variable was not significant in the multivariable model and was therefore not included in the final model
eOdds ratio interpreted as odds of agreeing to follow-up per one partner increase
fEnrollment in the follow-up survey was limited to white non-Hispanic, black non-Hispanic, and Hispanic participants
gItalicized odds ratio and confidence interval denote significance at P < .05
hParticipants could write in a text response for sexual identity; most frequent responses were “queer,” “curious,” and “questioning”
iGED: general equivalency diploma
jUAI: unprotected anal intercourse
kExchange partner defined in the survey as “someone who you have sex with in exchange for money, drugs, food, or something else of value”
