2 Short-chain dicarboxylacylcarnitine (SCDA) levels predict cardiovascular events.
Short-chain dicarboxylacylcarnitine (SCDA) levels predict cardiovascular events. Unadjusted (A) and adjusted (B) Kaplan–Meier curves demonstrating increasing risk of death with higher baseline levels of SCDA metabolites; (C) risk reclassification analyses showing incremental risk prediction to 23-variable clinical model (net reclassification index, 8.8%).

3 Visual representation of omics technologies available for integrated analyses.
Visual representation of omics technologies available for integrated analyses. Molecular changes reflected in these markers, in combination with environmental influences, result in the health or disease phenotype. GC indicates gas chromatography; MS, mass spectrometry; and NMR, nuclear magnetic resonance. Reprinted from Lewis et al24 with permission of the publisher. Copyright © 2008, Elsevier. Svati H.

4 Manhattan plot of genome-wide association studies (GWAS) of metabolites from the KORA study.
Manhattan plot of genome-wide association studies (GWAS) of metabolites from the KORA study. Displayed is the strength of association with metabolite concentrations (top; P<10−7 in red) and concentration ratios (bottom; P<10−9 in red).

5 Genetic networks of liver metabolism revealed by integration of metabolic and transcriptional profiling. Genetic networks of liver metabolism revealed by integration of metabolic and transcriptional profiling. Results from a study of F2 intercross between diabetes mellitus–resistant C57BL/6 leptinob/ob and diabetes mellitus–susceptible BTBR leptinob/ob mouse strains: (A) metabolic quantitative trait loci (mQTL) mapping identifying genetic hotspots for metabolite regulation and (B) causal network analysis links gene expression and metabolic changes in the context of glutamate metabolism. LOD indicates logarithm of the odds. Reprinted from Ferrara et al34. Svati H. Shah, and Christopher B. Newgard Circ Cardiovasc Genet. 2015;8: Copyright © American Heart Association, Inc.
