For the CD4+ lymphocytes >500 cells/μL endpoint, the variables that remained statistically significant throughout the analysis were: (i) no history of AIDS at baseline (HR: 5.28 (IQR: 1.91–14.63), p = 0.001) and (ii) a viral load <5 log copies/mL (HR: 2.13 (IQR: 1.26–3.59), p = 0.004; (Figure 3). This evidence concerns the gene CD4 and AIDS.
