Global structure of the hierarchical map. a–c Absolute number and percentage of significant intra-fluid and interfluid edges. The percentage is calculated as the number of edges divided by all possible edges. d–f Number of intrafluid edges occurring in only one fluid or shared across two or all three fluids. Black numbers correspond to links between metabolites, sub-pathways, or super-pathways that were measured in all the three body fluids, while gray numbers represent metabolites and pathways that occur in at most two body fluids
