Cost-utility of a walking programme for moderately depressed, obese, or overweight elderly women in primary care: a randomised controlled trial

Table 4 The EQ-5D utilities of the exercise programme compared to usual care

Alternatives	Best care in general Practice (n = 51)	Best care plus Exercise (n = 55)
EQ-5D utility at baseline	0.542 (0.334)	0.688 (0.304)
EQ-5D utility at 6 months*	0.510 (0.196)	0.890 (0.178)
QALY over 6 months*	0.263 (0.132)	0.395 (0.121)
QALY difference versus best care†		0.132 (0.104 to 0.286)
Incremental cost per person (€)		41
Cost-utility (€/QALY) †		311 (143 to 394)

Expressed as mean (SD)
QALY = quality adjusted life year
*Mean (SD) estimated by analysis of covariance with adjustment for baseline EQ-5D score and then rounded to three significant figures.
† Mean (95% confidence interval estimated by bootstrapping).
