The incidences of decompensated cirrhosis (defined by ascites, hepatic encephalopathy, or bleeding esophageal varices), hepatocellular carcinoma (HCC), and liver-related mortality among patients infected with hepatitis C virus (HCV) who achieve a sustained viral response (SVR), compared with patients who fail treatment (treatment failure), are unclear. We performed a meta-analysis to quantify the incidences of these outcomes.

This meta-analysis included observational cohort studies that followed HCV treatment failure patients; data were collected regarding the incidence of decompensated cirrhosis, HCC, or liver-related mortality and stratified by SVR status. Two investigators independently extracted data on patient populations, study methods, and results by using standardized forms. The agreement between investigators in data extraction was greater than 95%. Data …
