Figure 2.

Pathway analysis of metabolites with significant differences in signal between the delirium and control groups. A red box indicates an input metabolite, and all are upregulated in delirium. The two most significantly enriched pathways are (a) arginine biosynthesis (FDR = 0.0011) and (b) pentose phosphate pathway (FDR = 0.00011). Supplementary Figure S4 contains the original pathway figures generated through MetaboAnalyst, including KEGG compound numbers.
