SECONDARY outcome

Timeframe: Screening and 12 weeks post end of treatment (SVR12)

Change in health-related quality of life score pre and post-treatment (measured by EQ-5D-3L). The EQ visual analogue scale records the patient's self-rated health on a vertical visual analogue scale where the endpoints are labelled 'Best imaginable health state' (value of 100) and 'Worst imaginable health state' (value of 0). The VAS can be used as a quantitative measure of health outcome that reflects the patient's own judgement. Higher scores indicate better outcomes.
