a ICERs for the comparison between PICT and VCT, b ICERs for the comparison between HBT and VCT. *Black vertical solid lines represent base-case results. Note: the area shaded red covers all negative ICERs and represents a dominated scenario by VCT for the strategy under comparison. Black dotted lines demarcate the range of ICERs for each comparison that would result from the corresponding ranges of HCT unit costs. a The shaded area between the lower black dotted line and the origin represents the likelihood that base-case ICER was not robust and a dominated scenario for PICT. b The area enclosed by both dotted lines lie within the shaded region, suggesting base-case findings that HBT was dominated were robust up to this range of unit costs. VCT voluntary counselling and testing, PICT provider-initiated counselling and testing, HBT home-based testing, ICER incremental cost-effectiveness ratios
