For example, baseline anemia (Hgb < 10 g/dL) [5, 9], low CD4 count [5], advanced WHO clinical disease staging (III & IV) [5, 9], poor ART drug adherence [10], and malnutrition [11] were reported as factors significantly increasing risk of mortality in HIV-positive children receiving ART. This evidence concerns the gene CD4 and anemia (phenotype).
