  • *At-risk partners were those perceived by study participant to be HIV-negative or of unknown serostatus at the time of the sexual activity.

  • †There were five transgender participants. They were omitted as a separate subgroup of the gender/sexual orientation variable, but were retained in the other variables in this table.

  • ‡This does not reflect whether the patient is a current injection drug user.

  • §There was one case of missing data on this variable.

  • ART, antiretroviral therapy; CASI, computer-assisted self-interview; MSM, men who have sex with other men.
