Fig. 3

Cost-effectiveness plane showing the incremental benefits (CPE acquisitions avoided/1000 admissions) and costs relative to the least expensive strategy (baseline). Strategies (1, 2, 4, 5, 6, 7, 8, 10, 11) are dominated. The efficiency frontier (black line), joins the non-dominated strategies and the ICER between a specific strategy and the next, more costly, but more effective is presented
