EuroQol 5-dimension, 5-level (EQ-5D-5L) Quality of Life Questionnaire

Patients are asked to rate their perception of their health on the day they complete the assessment on a scale of 0 to 100. A score of 100 means the patient has the best health they can imagine, and a score of 0 means the worst health they can imagine. The reported value is the average of all patient scores reported at the specified time point for the specified patient group.

Time frame: 30 Days
