Cost-effectiveness Plane Displaying Incremental Costs and QALYs and Cost-effectiveness Acceptability Curves and Probability Estimate of the Intervention Compared With Usual Care at the Specified Willingness-to-Pay Thresholds
CHRONIC HEADACHE
(A) The graph shows the cost-effectiveness plane displaying 1,000 base-case ICERs simulated from the joint distribution of incremental costs and incremental QALYs. (B) Graph represents cost-effectiveness acceptability curves and gives a probability estimate of the CHESS intervention being cost-effective compared with usual care at the specified willingness-to-pay thresholds. Abbreviations: CHESS = Chronic Headache Education and Self-management Study; ICER = incremental cost-effectiveness ratio; QALY = quality-adjusted life year.
