For all HIV/AIDS patients, the main risk factors related to non-AIDS-associated mortality were age greater than 60 years, compared to younger than 60 years (HR 5.755, 95% CI 3.814–8.683), late diagnosis, compared to early diagnoses (HR 2.277, 95% CI 1.618–3.205), infection by heterosexual contact, compared to infection by homosexual contact (HR 2.134, 95% CI 1.340–3.399), and last CD4+ T cell count (100–199 cells/mm3: HR 0.353, 95% CI 0.230–0.543; 200–499 cells/mm3: HR 0.234, 95% CI 0.164–0.334; ≥500 cells/mm3: HR 0.040, 95% CI 0.102–0.175, compared to CD4 + T-cell count <100 cells/mm3). Here, CD4 is linked to infection.
