Metabolic Profiling Study of Yang Deficiency Syndrome in Hepatocellular Carcinoma by NMR and Pattern Recognition
Figure 2
Results after PLS-DA using the 1H NMR spectra of serum from HCC patients. (a) PLS-DA score plot shows a clear separation between Yang deficiency syndrome patients with HCC (YDS-HCC) (■) and non-Yang deficiency syndrome patients with HCC (NYDS-HCC) (▲). (b) Examination of the corresponding loading plot indicated that those variances out of the ellipse were responsible for the separation of YDS-HCC and NYDS-HCC patients marked with chemical shift (ppm).
