We investigated the association of several factors with the rate of CD4 recovery, including age, CD4 nadir (defined as second lowest CD4 count), baseline VL (available for 60/79 participants), duration of pre-ART immunosuppression, duration of time with HIV infection, and prior status as a long-term non-progressor (HIV+ for ≥10 years with CD4 ≥500). The gene discussed is CD4; the disease is HIV infectious disease.
