KRT19 and hepatocellular carcinoma: The results showed that ultrasomics signatures based on machine-learning could predict and classify the expression of CK19 in HCC.As can be seen from Table 2, the combined model incorporating ultrasomics signatures and clinical factors performed excellently, with AUC improving to 0.867 (95% CI, 0.712 – 0.957) and 0.862 (95% CI, 0.703 – 0.955), respectively.
