Protein interactions and functional prediction of the 26 most homogeneous factors quantified in ASC-CM samples. (a) List of the 26 selected factors having a coefficient of variation below 33% () and (b) corresponding protein-protein interactions uncovered by STRING analysis. (c) Top 15 KEGG pathways associated with the 26 proteins selected based on false discovery rate (FDR) value (-log₁₀ FDR values are reported as orange bars). Fold enrichment was calculated as follows: and is reported as blue bars.
