Cost-effectiveness analysis: Base case and sensitivity analysis. Abbreviation: LEEP, loop electrosurgical excision procedure. Incremental cost-effectiveness ratios (ICERs) for the phase 2 screen and treat (ST) strategy are presented along the x-axis in 2014 US$ per year of life saved for the base case analysis and sensitivity analyses (y-axis). The orange bars represent the range of the ICERs for ST (dominant strategy) across the 50 input parameter sets, with the ICER of the mean costs divided by the mean effects demarcated by a black line. The dashed black line indicates El Salvador's per capita gross domestic product (GDP) at US$3990, which was considered as a threshold for identifying very cost-effective interventions.
