Plots of 2000s-order Monte-Carlo simulations of incremental cost per proportion linked to care gained on high cost/worse outcome and low cost/worse outcome quadrants of the cost-effectiveness plane. a Monte-Carlo simulations for the comparison between PICT and VCT; b Monte-Carlo simulations for the comparison between HBT and VCT. *Interpretation of ICERs in the low cost/worse outcome quadrant is dependent on the WTA threshold. #ICERs in the high cost/worse outcome quadrant represent a dominated scenario for the strategy under comparison. Note: The red ellipse of confidence encircles 95% of the bootstrapped ICERs, and black solid lines represent quasi 95% confidence intervals a ICERs have almost equal chance of falling into the high cost/worse outcome and low cost/worse outcome quadrants. b ICERs are more likely to fall in the high cost/worse outcome quadrant. PICT provider-initiated counselling and testing, HBT home-based testing; VCT voluntary counselling and testing, ICER incremental cost-effectiveness ratio, WTA willingness to accept
