Figure 3. — Abbreviations: CE, cost-effectiveness; DALY, disability-adjusted life-year; USD, US dollar.

This figure shows the probability that the aerial logistics intervention is cost-effective at varying willingness-to-pay (WTP) thresholds per averted DALY, from both the government or health system perspective (red) and societal (blue) perspectives. The cost-effectiveness acceptability curves are derived from probabilistic sensitivity analysis. Vertical dotted lines indicate the WTP thresholds at which the intervention reaches 95% probability of being cost-effective: $200 under the government perspective and $680 under the societal perspective. The curves illustrate the higher certainty of cost-effectiveness under broader societal valuation.
