| HIV-transmission risk factors§ | IDU | 558 (29) | 335 (40) | Referent |
| MSM | 701 (38) | 279 (33) | .65 (.54–.79) | |

| < 200 cells/mm3 | 913 (49) | 297 (44) | .80 (.67–.95) |
Included, first CD4+ T-cell count within 6 months of first reported positive HIV test
Excluded, first CD4+ T-cell count missing (165 persons) or more than 6 months after first reported positive HIV test (682 persons)
OR = odds ratio. The ratio of the odds of being excluded to the odds of being excluded in the referent group; 95% CI, 95% confidence interval. 95% CI's for sex, race, age, and first CD4+ T-cell count are from chi-square tests, and those for the transmission risk categories are from a logistic regression analysis of the transmission risk categories over the outcome. Results that are significant at the 95% level are in bold type.
IDU = injection drug users (including men who have sex with men as well as inject drugs); MSM = men who have sex with men; all heterosexual, both high-risk heterosexual (persons who have heterosexual contact with persons known to be HIV-positive or to have a risk factor for HIV infection) and presumed heterosexual (persons who have heterosexual contact and do not have any other known risk factors); others, persons with blood contact or no identified risk
