PCAs of omics and clinical/lifestyle/diet data. Biplots are shown for five distinct PCAs using the respective first two axes of variations from each PCA. The five PCAs correspond to the analysis of: a 101,099 autosomal SNPs pseudo-randomly chosen to minimize linkage disequilibrium between the SNPs; b 21,649 gene transcript probesets; c 274 miRNAs; d 282 lipid species; e a set of 284 clinical, lifestyle, and dietary variables; and f only the 199 dietary variables. Each circle represents an individual from the iOmics and is assigned a color corresponding to the self-reported ethnicity of the subject, according to the color legend on the top right panel in a
