The study assessed patient utility with the use of the EQ-5D health survey in the Fractional Flow Reserve Versus Angiography for Multivessel Evaluation 2 (FAME 2) trial and found that percutaneous coronary intervention of coronary lesions with abnormal fractional flow reserve was more economically attractive than best medical therapy. However, we have some concerns with the statistical analysis.
Cost–utility analysis is a common comparative effectiveness methodology in current health economics research, and quality-adjusted life-year …
