Figure 3. The cost-effectiveness frontier of different strategy combinations.

The cost-effectiveness frontier (solid line) includes strategies that maybe cost-effective if the incremental cost-effectiveness ratio is less than the accepted threshold. Strategies that are not on the frontier are dominated, meaning that they are not efficient use of resources. In figure 3.A, irrespective of the feeding patterns, remedial cohort is less cost-effective. In figure 3.B, mothers' prompt treatment and replacement feeding cohort is the most cost-effective intervention, followed by the promptly treated cohort being assigned to breastfeeding.
