Adjusted Subdistribution Hazard Ratios (HR) and 95% Confidence Intervals (95% CI) for Discontinuity, Isolating the Impacts of Sex, Race, and IDU HIV Risk Within Vulnerable Populations
| Vulnerable population | HR | (95% CI) |
|---|---|---|
| Among MSM males alone | ||
| Black vs. nonblack | 1.16 | (1.05, 1.27) |
| Among non-MSM males alone | ||
| Black vs. nonblack | 1.21 | (1.13, 1.29) |
| IDU vs. non-IDU | 1.31 | (1.22, 1.4) |
| Among females alone | ||
| Black vs. nonblack | 1.05 | (0.94, 1.17) |
| IDU vs. non-IDU | 1.16 | (1.01, 1.34) |
| Among black, non-IDU patients alone | ||
| Non-MSM male vs. non-IDU female | 1.26 | (1.14, 1.4) |
| MSM male vs. non-IDU female | 1.08 | (0.97, 1.2) |
| Among white, non-IDU patients alone | ||
| Non-MSM male vs. non-IDU female | 1.18 | (0.98, 1.43) |
| MSM male vs. non-IDU female | 1.08 | (0.92, 1.26) |
Each model accounted for competing risk of death before discontinuity and adjusted for age, baseline CD4+ count, nadir CD4+ count after ART initiation, and cohort site.
Bold estimates are statistically significant (p < 0.05).
