Description of intervention(s) / exposure
Exposure to thyroid disease confers a favorable sustained virologic response in chronic hepatitis C undergoing combination therapy. Patients who developed thyroid disease during treatment with Interferon and Ribavirin will be observed for 6 months after end of treatment to ascertain viral outcome.

Not applicable
Comparator / control treatment
This is a nested case control study. The historical data was collected over a 5 year period from 2005-2008, including sustained virologic response in chronic hepatitis C patients without thyroid disease.
Control group
Historical

Outcomes
Primary outcome [1] 259298 0

Sustained virologic response is defined as undetectable Hepatitis C virus-ribonucleic acid (HCV-RNA) by polymerase chain reaction (PCR) tests at 6 months after completion of combination treatment.
Timepoint [1] 259298 0
Six months after the completion of above treatment.
