The present study aimed to provide normative data for the EQ-5D-5L questionnaire in Bulgaria, based on a nationally representative sample. ⋯ Bulgarian population norms, which were developed for the descriptive part of the EQ-5D-5L and EQ VAS, can be used as reference values. The availability of such normative data should encourage the use of the EQ-5D-5L questionnaire in health-related quality-of-life studies in Bulgaria.
