Fig. 3From: Cost-effectiveness of a hybrid emergency room system for severe trauma: a health technology assessment from the perspective of the third-party payer in JapanDeterministic sensitivity analysis. The tornado diagram showing the results of worst and best case scenario based on the plausible ranges of the parameters. The vertical solid line represents the willingness-to-pay threshold ($47,619), and the vertical dotted line represents the ICER from the base-case scenario ($32,522). Horizontal bars represent the estimated ICERs based on the plausible range of the parameters. ER, emergency room; ICER, incremental cost-effectiveness ratioBack to article page
