Cost-effectiveness analysis of patent foramen ovale closure versus medical therapy alone after cryptogenic stroke
Fig 4
One-way sensitivity analysis: The stable state utility score difference between PFO closure and medical therapy.
The stable state utility score difference between PFO closure and medical therapy, which is the largest impact of parameter variation, is shown with ICER. The dashed line represents a willingness-to-pay (WTP) threshold of $50,000 /QALY and a utility score difference of 0.051 at that WTP threshold. Abbreviations. WTP, willingness-to-pay; ICER, incremental cost-effectiveness ratio.
