The tumor diagnostic model was formulated as follows: logit (P-HCC) = -2.534 – 1.240 * SOCS2 expression level - 1.320 * LCAT expression level + 0.335 * FTCD expression level – 1.911 * KRT17 expression level + 4.422 * PBK expression level + 2.006 * CBX2 expression level. Here, KRT17 is linked to hepatocellular carcinoma.
