Comparison of the Multiattribute Utility Instruments EQ-5D and SF-6D in a Europe-Wide Population-Based Cohort of Patients with Inflammatory Bowel Disease 10 Years after Diagnosis

Table 6

EQ-5D and SF-6D index scores that depend on subjectively perceived health derived from question one in SF-36.

	Self-perceived health ()	Mean	95% CI	Median
EQ-5D	Excellent (56)	0.96	0.92–0.99	1.0
	Very good (212)	0.93	0.91–0.95	1.0
	Good (315)	0.84	0.82–0.86	0.85
	Fair (155)	0.62	0.58–0.66	0.69
	Poor (31)	0.31	0.21–0.41	0.19
SF-6D	Excellent	0.91	0.89–0.94	0.93
	Very good	0.85	0.83–0.86	0.89
	Good	0.78	0.77–0.80	0.80
	Fair	0.64	0.63–0.66	0.62
	Poor	0.54	0.52–0.57	0.54

Significance levels of differences per utility instrument between the utility index scores due to different health states: (between excellent and very good in EQ-5D); (ANOVA). Question one in SF-36: “In general, would you say your health is: excellent, very good, good, fair, poor?”
