Figure 5.
One-way sensitivity analysis of key model parameters to assess changes in the incidence threshold for either strategy. This analysis tested the effect of varying single model parameters for cost, disability, and epidemiology on the cost-effective incidence threshold for vaccination through the Expanded Program on Immunization (EPI) relative to no vaccination (A) and routine immunization through the EPI with a school-based catch-up campaign relative to routine immunization through the EPI alone. The horizontal axis depicts the incidence (cases/100000) at which the strategy was highly cost-effective (willingness to pay of $1035/averted disability-adjusted life-year [DALY]). Each model parameter is presented with the base case value, and lower and upper range in parentheses.
