Low agreement warrants caution against interchangeable EQ-5D/SF-6D use in coronary stenosis; leaves open the preferred utility instrument for this population.
Does the SF-6D yield comparable utility scores to the EQ-5D in patients with symptomatic coronary stenosis?
The EQ-5D and SF-6D instruments yield incomparable utility scores in patients with coronary heart disease, highlighting that the choice of instrument significantly impacts quality of life assessment.
