Figure 5.

One-way sensitivity analysis of the cost-effectiveness of 50% PrEP + 90% ART, compared with the base case (no PrEP + 77% ART). The horizontal bars represent the range of the incremental cost-effectiveness ratios (ICERs) as each parameter varies across its plausible range. The bars with negative ICERs in some cases are marked as ‘cost-saving’. The solid vertical black line indicates the base case ICER ($45,222 per QALY gained). The dashed vertical blue and red lines represent the GDP per capita in Jiangsu Province, China ($18,100 in 2020)⁴⁹ and three times the GDP per capita, respectively. ICER<GDP per capita or GDP per capita <ICER<3GDP per capita denote that the strategy is highly cost-effective and cost-effective. PrEP, pre-exposure prophylaxis; ART, antiretroviral therapy; ICER, incremental cost-effectiveness ratio; QALY, quality-adjusted life-year; GDP, gross domestic product.
