The tumor diagnostic model was formulated as follows: logit (P-HCC) = 6.906 - 0.494 * SOCS2 expression level - 1.250 * LCAT expression level – 0.493 * FTCD expression level + 0.602 * KRT17 expression level + 1.950 * PBK expression level + 7.243 * CBX2 expression level. Here, CBX2 is linked to hepatocellular carcinoma.
