ROC curve analysis was performed to evaluate the diagnostic value of five DElncRNAs (HAND2‐AS1, ENSG00000232855, HCG25, LOC105378687 and LOC101927043), five DEmRNAs (RND3, LART, RCAN1, KIFC1 and CDC20) and four DEmiRNAs (miR‐424, miR‐93, miR‐224 and miR‐877) for HCC. The gene discussed is RCAN1; the disease is hepatocellular carcinoma.
