HMGA1 and hepatocellular carcinoma: Figure 4B shows the ROC curves of the five genes for diagnosing HCC. The AUC values of the five genes were as follows: 0.701 for CETN2 [95% CI: 0.608–0.783], 0.812 for HMGA1 (95% CI: 0.728–0.879), 0.731 for MPZL1 (95% CI: 0.639–0.809), 0.890 for RACGAP1 (95% CI: 0.818–0.941), and 0.765 for SNRPB (95% CI: 0.676–0.839).
