Fig. 5From: Integrated plasma metabolomics and lipidomics profiling highlights distinctive signature of hepatocellular carcinoma in HCV patientsA–D Graphical representation of confusion matrices obtained from PLS-DA models (metabolomics A, lipidomics B) of both independent modalities for the test phase classifying AFP-negative HCC patients. The ROC curves (metabolomics C, lipidomics D) reported compares the models’ performances reducing the number of variables to the VIPs and the first 20 VIPsBack to article page
