An essential guide to standard value sets for EQ-5D-5L is now available to download. The book includes a comprehensive inventory of published standard EQ-5D-5L values sets, providing a structured summary of each, as well as a comparative review of their characteristics. The book also includes a user guide, providing clear guidance to researchers on how to choose a value set, and for what purpose. The Forwards are by Mike Drummond and Kim Rand. This easy-to-use resource is likely to become a key text for EQ-5D-5L users and researchers.
