Figure 4. Partial Least Squares Discriminant Analysis of NMR spectra acquired on blood serum samples.

Figure 4

Scores (A) and weights (on LV1; B) plots obtained from OSC-PLS-DA performed on the NMR spectra of 52 blood serum samples. Group B (solid green, 27 samples): patients after chemotherapy; group C1 (solid blue, 10 samples): sustained remission; group C2 (empty blue, 15 samples): in relapse after chemotherapy. Lac: lactate; Gly: glycine; Tau: taurine; Cho: choline; Suc: succinate; Pyr: pyruvate; Ace: acetate; 2HiB: 2-hydroxyisobutyrate.
