CD4 and AIDS: In multivariate model, adjusted for AIDS history, lymphocyte CD4 baseline and nadir <200 cells/μL, last lymphocyte CD4 < 500 cells/μL, HIV viral load at baseline <5 log copies/mL and transmission route, virologic treatment efficacy, expressed as HIV-1 viral load <50 copies/mL proved similar across the analysed treatment groups (Figure 3).
