Figure 1.
BED theoretical power as a function of the HIV incidence rate to HIV prevalence ratio.
Results were obtained by simulations. The figure represents the BED theoretical power among young men and women as a function of the HIV incidence rate to HIV prevalence ratio for the baseline scenarios.

BED theoretical power needed to obtain a statistically significant HIV incidence rate ratio among young people when using BED incidence testing; results were obtained by simulations.

Figure 2.
HIV prevalence by age obtained among uncircumcised men of the Orange Farm Community.
This figure represents the HIV prevalence by age, with 95% confidence intervals, obtained among a random sample of uncircumcised men of the Orange Farm (South Africa) Community in 2007. A linear regression line has been added to the data.
