Figure 4.

Relevance network plots of significant omics features from the discrimination of AMI vs. healthy patients, displaying (A) key cluster amongst all four omics with strong correlations between features (r ≥ 0.67; p-value < 0.05), and (B) tri-omics (glycomics + metallomics + lipidomics) correlations (r ≥ 0.5; p-value < 0.05). The color key indicates the correlation coefficient values annotated by the connection lines between variables. Red colored connection lines denote positive correlations, while green colored connection lines denote negative correlations between variables. The intensity of the colors is scaled according to the magnitude of the correlation coefficient values.
