Figure 3. Monte Carlo Simulations of Incremental Cost and Incremental Quality-Adjusted Life-Years (QALY) of Mechanical Thrombectomy With Standard Medical Care for the Full Population.

A, The results are shown as scatterplots of incremental costs and incremental QALYs of mechanical thrombectomy with standard medical care vs standard medical care alone per patient with acute ischemic stroke for the full population per trial. Each dot represents 1 simulation run. The black lines indicate 3 different willingness-to-pay thresholds per QALY. The number of dots below a specific line represent the probability for mechanical thrombectomy with standard medical care to be cost-effective at the related WTP threshold. B, Each curve shows the probability that mechanical thrombectomy with standard medical care is cost-effective at different values of willingness to pay for a QALY for the full population and different subgroups. Curves for the SMC alone strategy are not shown.
