Furthermore, multivariate analysis identified six FR-lncRNAs risk scores for HCC (Supplementary Table S4), according to the following formula:Riskscore = PRRT3-AS1 * 0.101 + LNCSRLR * 0.769 + MKLN1-AS * 0.732 + LINC01224 * 0.524 + LINC01063 * 0.370 + POLH-AS1 * 1.06 Here, MKLN1 is linked to hepatocellular carcinoma.
