Figure 1
Figure 1 Receiver operating characteristic curves comparing prothrombin induced by vitamin K absence-II, alpha-fetoprotein and a combination of alpha-fetoprotein and prothrombin induced by vitamin K absence-II in patients with hepatocellular carcinoma vs those with nonmalignant chronic hepatitis B. The AUROC curves for PIVKA-II, AFP, and Combination are indicated in the inset. P = 0.965 for AFP vs PIVKA-II, P < 0.001 for combination vs PIVKA-II and P = 0.037 for combination vs AFP. PIVKA-II: Prothrombin induced by vitamin K absence-II; HCC: Hepatocellular carcinoma; AFP: Alpha-fetoprotein.

Figure 2 Receiver operating characteristic curves comparing prothrombin induced by vitamin K absence-II, alpha-fetoprotein and a combination of alpha-fetoprotein and prothrombin induced by vitamin K absence-II in patients with hepatocellular carcinoma vs those with liver cirrhosis. The AUROC curves for PIVKA-II, AFP, and Combination are indicated in the inset. P = 0.042 for AFP vs PIVKA-II, P = 0.001 for combination vs PIVKA-II and P < 0.001 for combination vs AFP. PIVKA-II: Prothrombin induced by vitamin K absence-II; HCC: Hepatocellular carcinoma; AFP: Alpha-fetoprotein.
