From: Targeted metabolomics profiling in pregnancy associated with vitamin D deficiency
Metabolic enriched activity network of serum polar metabolites in vitamin D deficient pregnant women. Red/blue nodes represent higher/lower intensity in vitamin D deficient pregnant women. Yellow nodes represent similar levels of metabolites between vitamin D deficient versus sufficient samples. Blue edges represent the enzyme(s) between two metabolites that were inactivated. Metabolites that had no direct relationship were linked by dotted lines. Black dashed edges represent activity of enzyme(s) without statistical significance
