Abbreviations: CS, cost-saving; HIV, human immunodeficiency virus; ICER, incremental cost-effectiveness ratio; IP, infections prevented; LYG, life-years gained; PrEP, preexposure prophylaxis.
a Undiscounted new infections and infections prevented are shown.
b Costs and life-years shown are discounted 3% annually. Cost and health outcomes are discounted 3% annually in ICER calculations. ICERs shown are calculated relative to the reference scenario.
