Monte Carlo scatter plot: incremental cost-effectiveness of ECMO bridged transplant versus transplant alone. Monte Carlo plots show repeated random samples from the model are depicted by one dot, which represents the average quality adjusted life year (QALY) gained and the incremental cost of that sampling based on the model. The 0-value horizontal line demarks the point above which, the intervention is not cost effective. The inclining line represents the willingness to pay (WTP) threshold. Above this line, the intervention is efficacious but not cost effective. The red dots demonstrate the simulated incremental cost estimate above the willingness to pay threshold of $50,000 whereas the green dots demonstrate estimates below the WTP threshold. The scale represented by dollar amount along the Y axis among the transplanted patients is narrower than for left ventricular assist device patients. Fewer simulations identified incremental cost estimates below the willingness to pay threshold in contrast to those that exceed it. ECMO, Extracorporeal membranous oxygenation.
