Multivariate models for factors associated with risk of first clinical AIDS or death event.

1<p>Model 1 (Overall) includes 754 people with 116 events.</p>2<p>Model 2 (Censored at HAART initiation) included 425 participants with 83 events.</p>3<p>Model 3 (CD4 ≥500 at last HBV vaccination) included 391 participants with 31 events.</p>4<p>Viral load was not included in Model 2 because there were no events in the 23 participants with viral load ≤400 copies/mL.</p><p>NOTE. HR, hazard ratio; CI, confidence interval; DTH, delayed type hypersensitivity; HAART, highly active antiretroviral therapy; Anti-HBs, hepatitis B surface antibody; ND, not done; N/A, not applicable. All three models were adjusted for duration of HIV infection at the time of last vaccination (per 6 months), and known HIV seroconversion status. Models 1 and 3 were also stratified for HIV diagnosis era (pre-1996 versus 1996 or later).
