Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Sustained virological response (SVR)	The primary outcome measure is the occurence (yes or no) of sustained virologic response (SVR), defined as HCV RNA < the lower limit of quantitation (LLOQ; ie, 15 IU/mL) in serum at least 3 months after stopping therapy. Point estimates and confidence intervals will be calculated to describe the frequency of SVR in various patients receiving IFN or DAAs based treatment.	36 months
Secondary	Treatment persistence	Treatment persistence will be the duration of treatment measured from the first dose of medication until treatment is discontinued. Reasons for premature discontinuation of treatment will be recorded.	36 months
Secondary	Virological breakthrough	The occurrence of virological breakthrough defined as an increase of HCV RNA by at least 1-log over nadir or to >100 IU if previously undetectable.	36 months
Secondary	Liver disease progression	Liver disease progression is a composite endpoint measured by laboratory parameters (alanine aminotransferase (ALT), aspartate aminotransferase (AST), bilirubin, albumin, platelets, prothrombin time (PT) and a-fetoprotein) and observed or reported clinical signs and symptoms.	Post treatment 10 years
Secondary	Proportion of participants who develop hepatocellular carcinoma (HCC) through Year 10 by treatment regimen		Post treatment 5 years
