Figure 4. PLS-DA score plot and its corresponding loading plot based on UPLC-MS profiling data of serum samples.

Figure 4

(A) PLS-DA score plot in control group (Inline graphic), tumor model group (Inline graphic) and FAE treatment group (Inline graphic) detected in positive ion mode, with fitting and predictive performance (3 latent variables, R2X = 0.478, R2Y = 0.825, Q2 = 0.36). (B) Loading plot in three groups detected in positive ion mode. (C) PLS-DA score plot in control, tumor model and FAE treatment groups detected in negative ion mode, with fitting and predictive performance (2 latent variables, R2X = 0.248, R2Y = 0.808, Q2 = 0.313). (D) Loading plot in three groups detected in negative ion mode. The variables with VIP >3.0 were highlighted with red filled circle (Inline graphic).
