As shown in Figure 2A, AFP (AUC = 0.850, P < 0.001) was the most valuable predictor for discriminating HCC patients from all controls, followed by DCP (AUC = 0.775, P < 0.001) and AFP-L3 (AUC = 0.763, P < 0.001), whereas GP73 had low diagnostic efficiency (AUC = 0.549, P = 0.053). Here, AFP is linked to hepatocellular carcinoma.
