OPLS-DA scores and permutation verification: scores of the OPLS-DA model with (a) 200 mM NaCl vs. CK (0 mM NaCl), (b) 500 mM NaCl vs. CK, and (c) 500 mM NaCl vs. 200 mM NaCl; OPLS-DA permutation analysis model verification chart of (d) 200 mM NaCl vs. CK, (e) 500 mM NaCl vs. CK, and (f) 500 mM NaCl vs. 200 mM NaCl. R2Y and Q2 represent the interpretation rate of the model to the Y matrix and the prediction ability of the model, respectively. A value closer to 1 means that the model is more stable and reliable, and when Q2 is > 0.9, the model is excellent. The horizontal line corresponds to the R2 and Q2 of the original model, and the red and blue points represent the R2’ and Q2’ of the model after Y replacement, respectively
