QALY, quality adjusted life year.

aMean (95% confidence interval) estimated by analysis of covariance with adjustment for baseline EQ-5D score and then rounded to 3 significant figures; bmean (95% confidence interval) using the area under the curve technique; cmean (95% confidence interval estimated by bootstrapping) using the area under the curve technique.
