Figure 1 The area under the receiver operating characteristic curves of the tumor markers for hepatocellular carcinoma diagnosis in the total population. AUROC: Area under the receiver operating characteristic curve; HCC: Hepatocellular carcinoma; AFP: Alpha-fetoprotein; AFP-L3: Lens culinaris agglutinin-reactive fraction of AFP; PIVKA-II: Protein induced by vitamin K absence or antagonist-II; NPV: Negative predictive value; PPV: Positive predictive value.

A: Training set; B: Validation set. AUROC: Area under the receiver operating characteristic curve; HCC: Hepatocellular carcinoma; AFP: Alpha-fetoprotein; AFP-L3: Lens culinaris agglutinin-reactive fraction of AFP; PIVKA-II: Protein induced by vitamin K absence or antagonist-II; ALPs: AFP, AFP-L3 fraction, and PIVKA-II.
