This Registry will enroll cirrhotic participants with or without decompensated liver disease who have achieved a sustained virologic response (SVR) after receiving a sofosbuvir (SOF)-based regimen without interferon (IFN) while participating in a Gilead-sponsored hepatitis C virus (HCV) study or commercially at selected sites. Once enrolled, participants will be followed for up to 5 years.
