The receiver operating characteristic (ROC) curves were used to detect the prediction accuracy of DPM1/2/3 in distinguishing the HCC from the normal samples compared with existed liver tumor markers containing alpha-fetoprotein (AFP), glypican-3 (GPC-3) and transforming growth factor- β1 (TGFβ1). Here, TGFB1 is linked to hepatocellular carcinoma.
