The clinical significance of hyperhomocysteinemia in cirrhosis and outcomes post\u2010liver transplantation is poorly documented. In this study, we aimed to determine the prevalence of hyperhomocysteinemia in cirrhosis, evaluate its association with thrombosis and severity of liver disease, and its impact on survival after liver transplantation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We analysed 450 patients with cirrhosis who received a liver transplant between 2001 and 2010.
