Fig. 4From: Cost-effectiveness of a hybrid emergency room system for severe trauma: a health technology assessment from the perspective of the third-party payer in JapanProbabilistic sensitivity analysis. a Cost-effectiveness scatterplot. Each plot shows a result of one simulation. Plots located in the first quadrants suggest that both cost and effect are higher in the hybrid ER system (trade-off) and plots located in the second quadrants suggest that cost is higher but effect is lower in the hybrid ER system (inferior). Plots reside under the dotted line of willingness-to-pay threshold suggest that the results of the simulations are cost-effective. b Cost-effectiveness acceptability curve. The line with square markers shows the probability that the conventional ER is cost-effective and the line with triangle markers shows the probability that the hybrid ER is cost-effective at each willingness-to-pay threshold.
