Fig. 4From: Serum metabolism alteration behind different etiology, diagnosis, and prognosis of disorders of consciousnessAnalysis of serum metabolomic of DoC patients with different prognoses. A OPLS-DA model based on patients’ serum metabolites for classification of patients with and without improvement after 3 months; B volcano plot for filtering differential metabolites (VIP value ≥ 1, fold change ≥ 1.5); C heatmap of differential metabolites in the two groups (blue indicate relative lower and red indicate relative higher in the group with higher CRS-R scores); D–F box plots for relative intensities of lysoPE(18:0/0:0), enantio-PAF C-16, and y-CEHCin DoC patients with different prognosisBack to article page
