*
Children in the archived samples cohort were initiated on ART soon after enrollment, while children in the real-time samples cohort had been on ART for 4 to 72 months at the time of enrollment.
a
CD4% results were available from N=88 children in the archived samples cohort, and were not collected from children in the real-time samples cohort.
b
CD4 count results were available from N=86 children in the archived samples cohort, and for N=20 children in the real-time samples cohort.
c
HIV-1 VL results were available from N=88 children in the archived samples cohort, and were not collected from children in the real-time samples cohort.
