Interpreting Metabolomic Profiles using Unbiased Pathway Models
Figure 5
Hierarchical clustering of changed metabolites (FDR<0.05) in IGT Group.
Grouping is according to 1−|ρ|, where ρ is the Spearman correlation coefficient for percentage change in metabolite abundance. Metabolite clusters that correspond to established transporter activities are highlighted. Cluster numbering is as in Figure 4.
