Figure 1
EuroQol-Five Dimensions (EQ-5D) receiver operating characteristic (ROC) curve. The ROC curve for the EQ-5D, taking the patient satisfaction index to be the anchor. The dashed line is a bootstrapped confidence interval. Also reported is the area under the curve and the 95% confidence interval and the defined minimum clinically important difference thresholds.
