aTotal number of records in each cycle's analysis is harmonized across the years within a cycle and includes the number of records that were eligible, consented to the survey, completed the interview, and provided valid answers.
bValid rapid or enzyme immunoassay test for HIV antibodies.
cSTI: sexually transmitted infection.
dHCV: hepatitis C virus.
eMSM: gay, bisexual, and other men who have sex with men.
fNot collected.
gPWID: persons who inject drugs.
hHET: heterosexually active persons at increased risk for HIV infection.
iThe first HET cycle was a pilot of the optimal operational definition of HET at increased risk for HIV as well as the optimal sampling strategy (venue-based sampling vs respondent driven sampling) to reach them. The first HET cycle was also the first population and cycle that HIV testing was offered in all project areas.
jYMSM: young men who have sex with men.
kAt least one valid test for gonorrhea or chlamydia from pharyngeal swabs (all cycles), rectal swab (MSM and Trans cycles only), vaginal swab (HET cycle only), or urine specimen (Trans cycle only).
lTrans: transgender women.
