Baseline variables associated with an increased risk of death that persisted after multivariate analysis were age category of older than 55 years compared to age category of 50–55 years (PR 1.47, p < 0.05), the presence of another AIDS-defining condition (not an OI or TB) at initiation (PR 2.28, p < 0.05), baseline ALT > 40 U/L (PR 1.53, p < 0.05) and baseline CD4+ < 100 cells/mm3 (PR 2.15, p < 0.05). This evidence concerns the gene GPT and tuberculosis.
