Among HIV-infected low BMI (-5.4 kj/kg/day, 95%CI: -10.4, -0.4), moderate anaemia (-13.8 kj/kg/day, 95%CI: -18.8, -8.8), CD4 counts ≤200cells/uL (-9.9 kj/kg/day, 95%CI: -16.5, -3.3) and log CRP (-9.7 kj/kg/day, 95%CI: -12.4,-7.0) were associated with lower PAEE. This evidence concerns the gene CD4 and anemia.
