One-way sensitivity analysis of PFO closure VS medical therapy.
The impact of parameter variation using a willingness-to-pay threshold of $50,000/QALY. The hatched bars and black bars show the upper (high estimate) and lower values of the parameter, respectively. Bars are aligned in order of impact from largest to smallest. Abbreviations. PFO, patent foramen ovale; mRS, modified Rankin Scale; DOAC, novel direct oral anticoagulants.
