Multivariate statistical analysis of metabolites. PCA scores plot for metabolomics between two groups. (A) T vs. N (Positive mode). (B) T vs. N (Negative mode). (C) Middle vs. Upper/Lower (Positive mode). (D) Middle vs. Upper/Lower (Negative mode). Applying OPLS-DA Analysis to evaluate the discriminant ability of the model. OPLS-DA score chart between two groups. (E) T vs. N (Positive mode). (F) T vs. N (Negative mode). (G) Middle vs. Upper/Lower (Positive mode). (H) Middle vs. Upper/Lower (Negative mode). Permutation tests for the OPLS-DA models. (I) T vs. N (Positive mode). (J) T vs. N (Negative mode). (K) Middle vs. Upper/Lower (Positive mode). (L) Middle vs. Upper/Lower (Negative mode). T, gastric cancer tissues; N, normal tissues; Middle, gastric cancer tissues located in middle third stomach; Upper/Lower, gastric cancer tissues located in upper/lower third stomach; vs., versus
