Note: *p < 0.001. For the ROC curve, p < 0.001 indicates that AUC is statistically significantly greater than 0.5 and that measure has discriminatory power
a RE of SF-6Dv2 is presented, and reference is EQ-5D-5L, of which RE is 1.000
Abbr: AUC Area under the ROC curve, 95% CI 95% confidence interval, RE Relative efficiency, ROC Receiver operating characteristic, SD Standard deviation
