aThe results reported here for alpha-fetoprotein levels correspond to increases of 100 units of alpha-fetoprotein levels; i.e., the hazard ratio of 1.01 means that every increase of 100 ng/ml is associated with a 1% increase in the hazard of death. HCC: hepatocellular carcinoma; MELD: model for end-stage liver disease.
