VL: Viral load; PP: per protocol; GM: geometric mean; CI: confidence interval; SD: standard deviation. Geometric means were calculated as the antilog of the mean (mean log10 VL set-point +1) -1.

aCalculated as the antilog{mean [(2012/1 log10 VL set-point +1)]}.

bPaired t-test on the difference in logged set-point values.
