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

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

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