Health-related quality of life measured with the EQ-5D-5L: estimation of normative index values based on a representative German population sample and value set.

This was the first study to estimate normative values of the EQ-5D-5L index for Germany based on a representative sample. The German normative values of the EQ-5D-5L are comparable to those reported for other countries. However, the mean EQ-5D-5L index score of the total sample was worse than those of the samples of studies from other countries.
