The variables associated to death were: Age > 40 years: HR Unadjusted = 1.8 (95% CI 1.1–3.0).-CD4+ <100 cell/μL, HR Unadjusted = 3.8 (95% CI 1.4–10.2).–AIDS, HR Adjusted = 13.5 (95% CI 1.4–132.3).-No HAART use, HR Adjusted = 96.5 (95% CI 17.0–546.3).  AIDS clinical stage [HR: 13.5, 95% CI (1.4 −132.3)] and lack of antiretroviral therapy [HR: 96.5, 95% CI (17.0–546.3)], were associated to a higher risk of dying. This evidence concerns the gene CD4 and AIDS.
