Fig. 4From: Incremental cost and cost-effectiveness of the addition of indoor residual spraying with pirimiphos-methyl in sub-Saharan Africa versus standard malaria control: results of data collection and analysis in the Next Generation Indoor Residual Sprays (NgenIRS) project, an economic-evaluationGlobal probabilistic sensitivity analysis results showing incremental cost-effectiveness ratio estimates for varied levels of incidence. Black points represent individual simulation results. Horizontal lines represent alternative cost-effectiveness thresholds: green solid line = 0.5 * per capita gross domestic product (PCGDP); dotted and dashed blue line represents 1 * PCGDP, and red dotted line represents 3 * PCGDP. The grey curve represents median ICER estimates at varied baseline incidence using the base case assumption of case fatality rate and red line represents median ICER estimates assuming a case fatality rate 50% lower than base case scenarios.
