a
Detectable or suppressed first viral load (dVL, sVL) are categorized using a cut-point of ≥400 copies/ mL or <400 copies/mL, respectively
b
Age at entry is continuous variable, thus we report ANOVA F- statistic
c
Lab values describe the mean proportion of all VL or CD4 tests above or below their respective cut-point per patient during the specified time period (mean % HIV RNA < 400 or ≥350 CD4 count during the first year or subsequent years)
d
Subsequent years indicates the observation time starting 12 months after the first visit until the last visit
