  1. Medians and interquartile ranges (in brackets) are shown for CD4+ T cell count and viral load measurements. Medians and ranges (in brackets) are shown for the number of days
  2. N/A not applicable
  3. aOne participant in the acute untreated group was diagnosed at Fiebig stage III, but her viremia was still on an upward trajectory. At the time of diagnosis, her viral load was 5.94 log10 RNA copies/mL which rose to 6.51 log10 RNA copies/mL at the next study visit
  4. bNadir CD4+ T cell counts were determined as nadir during the first 28 days after the detection of plasma viremia
  5. cSet point CD4+ T cell counts and set point viral loads were determined by calculating the averages between 28 days and 6 months after the detection of viremia in untreated individuals
  6. dStatistical tests used: Fisher’s exact test was used for % female and Fiebig stage at diagnosis; all other comparisons were done using the Wilcoxon rank-sum test
