Fig. 2

Heatmap of causal relationship between metabolites and allo-HSCT outcomes. Note: Only metabolites with significant associations in at least three allo-HSCT outcomes are shown in the figure. Red blocks represent high risk and blue blocks represent low risk. In addition, six different colors represent the pathways to which each metabolite belongs. Abbreviation: GVHD, graft-versus-host disease; FS, matched siblings; URD: matched unrelated donors
