This open access book is the first published guide about how to analyse data produced by the
EQ-5D one of the most widely used Patient Reported Outcomes questionnaires world wide. The
authors provide practical clear and comprehensive guidance in five concise chapters. Following
an overview of the EQ-5D and its analysis we describe how the questionnaire data - the EQ-5D
profile and EQ VAS - can be analysed in different ways to generate important insights into
peoples' health. We then show how the value sets which accompany the EQ-5D can be applied to
summarise patients' data. The final chapter deals with advanced topics including the use of
Minimally Important Differences case-mix adjustment mapping and more. This book is essential
for those new to analyzing EQ-5D data and will be also be valuable for those with more
experience. The methods can be applied to any EQ-5D instrument (for example the three- and
five-level and Youth versions) and many of the methodsdescribed will be equally relevant to
other Patient Reported Outcomes instruments.
