From: Metabolomics of bronchoalveolar lavage in children with persistent wheezing
Rank correlation heatmap between various metabolites in children with persistent wheezing. The heatmap showed a correlation matrix of various metabolite abundances in children with persistent wheezing (n = 30). Red represents a positive correlation, and green indicates a negative correlation. Noted significant correlations of butyrylcarnitine with palmitoylethanolamide, l-palmitoylcarnitine with choline, oleamide, palmitoylethanolamide and phosphatidylcholines
