Multivariable adjusted model includes the following variables: high-risk for HIV, use of fentanyl in the past three months, use of other opioids in the past three months, sharing injection equipment in the past three months, and prior awareness of PrEP.
Number of transgender / genderqueer / nonbinary persons was too small to run regression model.
Variable not included in the adjusted model, despite statistical significance in bivariate analysis, as person who are high-risk are by definition homeless and use methamphetamine.
In comparison to men who did not report sex with other men in the past 12 months.
