Figure 4. — Cost-effectiveness acceptability curves for disability-adjusted life years (DALYs) averted using focal mass drug administration (fMDA) or MDA with analysis based on either infections averted—community cohort surveillance—or cases averted—passive health facility surveillance. Vertical dotted lines represent the WHO thresholds for highly cost-effective (lower willingness to pay [WTP]) and cost-effective (higher WTP) in Zambia. The probability that intervention can be considered cost-effective can be read for any WTP threshold by finding the WTP value on the x-axis and reading the corresponding y-axis value for the specific intervention and effectiveness measurement method shown in the legend. WHO thresholds are indicative for Zambia and represent 1× and 3× gross domestic product per capita in Zambia.
