Clear separation of CPMG and LED spectra between NTG (red dots) and control (black boxes) groups. (a) Scores plot of OSC-PLS analysis of CPMG data; (b) corresponding loadings line plot. (c) Scores plot of OSC-PLS analysis of LED data; (d) corresponding loadings line plot. Keys to B: (1) lipid CH₃; (2) lipid CH₂; (3) lactate; (4) alanine; (5) acetate; (6) glutamate; (7) OAc; (8) pyruvate; (9) glutamine; (10), glycine. Keys to D: (1) lipid CH₃; (2) lipid CH₂; (3) lipid CH₂CH₂CO; (4) NAc; (5) lipid CH₂CO; (6) PUFA; (7) PtdCho; (8) lipid CH=CH (n = 10).
