Analysis of the metabolic correlation network based on significantly altered metabolites between young hypertensive men and healthy controls. (A) Metabolic correlation network based on 20 significantly altered metabolites (P < 0.05), containing 26 edges (T = 0.6). Yellow nodes represented hub metabolites of the network. (B) Three-dimensional diagram of three centrality indices for the 20 nodes of the network, including betweenness centrality, closeness centrality and degree centrality.
