MSM IDUs | 44/74 (59) | 1.55 (0.96, 2.52) | 1.73 (1.06, 2.83) | 10/55 (18) | 5.79 (2.65, 12.61) | 6.90 (3.11, 15.32) |

Non-MSM male IDUsc (Ref) | 441/908 (49) | 1.00 | 1.00 | 29/784 (4) | 1.00 | 1.00 |
Note. MSM = men who have sex with men; OR = odds ratio; AOR = adjusted odds ratio; CI = confidence interval.
ORs are for HIV prevalence for each gender or MSM behavior group relative to non-MSM male IDUs.
AORs are adjusted for age and race/ethnicity.
Whether or not male participants had sex with other men.
