The ROC of these nine DElncRNAs, AL356056.2, AL445524.1, TRIM52-AS1, AC093642.1, EHMT2-AS1, AC003991.1, AC008040.1, LINC00844, and LINC01018, were 0.750, 0.817, 0.905, 0.778, 0.927, 0.859, 0.722, 0.776, and 0.719, respectively (Figures 3(a)–3(i)), which indicated that these nine lncRNAs were related to HBV-linked HCC, playing a core role in estimating the onset of HBV-linked HCC. This evidence concerns the gene EHMT2 and hepatocellular carcinoma.
