From: Alterations in serum metabolomics predict drug-resistant epilepsy
Serum metabolomic profiles and multivariate analysis of metabolic separation between the NDRE and DRE groups. A Each metabolite’s relative expression across all samples is displayed in the heat map of the overall metabolite cluster. The expression is higher when the color is redder. The expression is lower when the color is bluer. B Hierarchical clustering dendrogram of epilepsy cohorts. Closer and shorter cluster trees represent higher similarity between samples. DRE, drug-resistant epilepsy; NDRE, non-drug-refractory epilepsy.
