5 lncRNAs with area under ROC curve (AUC) over 0.95 were selected for further analysis due to their potential roles in hepatocarcinogenesis and significant diagnostic value for patients with HCC, including HOXD antisense growth-associated long non-coding RNA (HAGLR), HAGLR opposite strand (HAGLROS), Surfactant associated 1 (SFTA1P), DDX11 antisense RNA 1 (DDX11-AS1) and AC092171.4 (Fig. 2). The gene discussed is HAGLR; the disease is hepatocellular carcinoma.
