From: 1H-NMR, 1H-NMR T2-edited, and 2D-NMR in bipolar disorder metabolic profiling
Metabolomics discriminate bipolar disorder patients from healthy individuals. a Plots of cross-validated PCA scores, 50 samples (25 BD + 25 HC) is equivalent to 150 spectra (75 BD + 75 HC). b 2D samples scores plot of PLS-DA, 76 samples (26 BD + 50 HC) is equivalent to 228 (78 BD + 150 HC). c Loadings Graph of spectral region δ 1.00 to 4.40 used in chemometrics. d 3D samples scores plot of PLS-DA
