Barta et al. (2014) defined a prognostic score for ARL by assigning weights to the HIV score (composed of CD4 count, viral load, and prior history of AIDS). However, it is still controversial whether HIV characteristics, such as viral load and CD4 count, influence prognosis in contemporaneously treated ARL (Barta et al., 2015; Ramos et al., 2020; Alderuccio et al., 2021). Here, CD4 is linked to AIDS.
