Comparison of the metabolome between HCC tissues and normal tissues. A Overall distribution trends of samples between the two groups by principal component analysis (PCA) and partial least squares discrimination analysis (PLS-DA). B Different colored points represent samples from different experimental groups, and ellipses represent 95% confidence intervals. C PLS-DA model validation based on sevenfold cross-validation and 200 permutation tests. D The overall distribution of differential metabolites. E Matchstick plots among differential metabolites
