Fig. 4From: Metabolomics approach by 1H NMR spectroscopy of serum reveals progression axes for asymptomatic hyperuricemia and goutSignificantly changed metabolites in patients with hyperuricemia (HUA) and patients with gout. a Numbers of significant metabolites. b Heatmap of significantly changed metabolites. The color of each section corresponds to a concentration value of each metabolite calculated by the peak area normalization method (red, upregulated; blue, downregulated)Back to article page
