When considering the diagnostic value of CD90 mRNA, the area under the curve (AUC, 95% CI) of the receiver operator characteristic (ROC) curve was 0.83 (0.76–0.90) (p < 0.0001), distinguishing non-tumoral distal to HCC from all samples in both cohorts. The gene discussed is THY1; the disease is hepatocellular carcinoma.
