Prognostic risk scores for liver transplantation: game changers or statistical artworks?

Several prognostic liver transplant-related risk scores for hepatocellular carcinoma(HCC)have been developed in recent years.The most prominent scores,displayed in Table 1,are based exclusively on HCC-related variables(1-6).Given that non-HCC-related variables can also influence post-transplant outcomes,Goldberg et al.sought to develop a continuous risk score predicting post-transplant survival for patients using both HCC-and non-HCC-related variables(1).
