The results of OPLS-DA score plots and 200-permutation tests. A, B OPLS-DA score plot and 200-permutation tests for normal and model group in positive ion mode (R2X = 0.371, R2Y = 0.976, Q2 = 0.742); C, D OPLS-DA score plot and 200-permutation tests for normal and model group in negative ion mode (R2X = 0.327, R2Y = 0.989, Q2 = 0.652); E, F OPLS-DA score plot and 200-permutation tests for model and LJF group in positive ion mode (R2X = 0.441, R2Y = 0.992, Q2 = 0.755); G, H OPLS-DA score plot and 200-permutation tests for model and LJF group in negative ion mode (R2X = 0.386, R2Y = 0.987, Q2 = 0.784). I OPLS-DA score plot for the three groups together in positive ion mode (R2X = 0.614, R2Y = 0.995, Q2 = 0.713). J OPLS-DA score plot for the three groups together in negative ion mode (R2X = 0.611, R2Y = 0.996, Q2 = 0.712)
