Volcano plot and hierarchical clustering of three groups. A Volcano plot based on GC–MS. B Volcano plot based on LC–MS. C Hierarchical clustering based on GC–MS. D Hierarchical clustering based on LC–MS. In (A, B), the blue dot represents metabolite with a downward trend, red represents metabolites with an upward trend, and the gray origin represents that the change of metabolites is not obvious. The area size of the point is related to the VIP value. In (C, D), the color from blue to red illustrates that metabolites’ expression abundance is low to high in hierarchical clustering. HCG: the healthy control group; HUA: asymptomatic hyperuricemia; AGA: acute gouty arthritis; LysoPC: lysophosphatidylcholine; PA: phosphatidic acid; PC: phosphatidylcholine; PGE2: Dinoprostone; PGF2α: Dinoprost; PI: phosphatidylinositol; PS: phosphatidylserine; SM: sphingomyelin
