Integrated analysis of metabolomics and proteomics. A Joint pathway analysis of differential metabolites and proteins. Metabolites and proteins were presented in circles and squares; proteins and metabolites enriched in BC patients and those with HC individuals were indicated by solid lines and dashed lines, respectively. Metabolites and proteins involved in the same metabolic pathways were connected by lines, and each pathway had a corresponding color. B Differential expression of those metabolites and proteins involved in these metabolic pathways between BC and HC groups. **P < 0.01
