Improvement in global quality of life (EQ5D-5L questionnaire) between enrolment and at 3 and 6 months after enrolment
The EQ5D-5L essentially consists of the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS).
There are five dimensions assessed in the descriptive system: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems.
Score from -0.53 to 1. A higher score means better outcome.
The EQ VAS records the patient's self-rated health on a vertical visual analogue scale, where the endpoints are labelled 'The best health you can imagine' and 'The worst health you can imagine'. The VAS can be used as a quantitative measure of health outcome that reflect the patient's own judgement.
Score from 0 to 100. A higher score means better outcome.
