  1. PLS-DA, orthogonal partial least squares discriminant analysis. Pair, comparison group name. Pre, master fraction. R2X, degree of explanation for model X variable data set. R2Y, degree of explanation for model Y variable data set. Q2, model predictability, a value closer to 1 indicates a more stable and reliable model, and a Q2 greater than 0.5 suggests good predictive ability. Pos, positive ion mode. Neg, negative ion mode. CK, the control group. SeNPs, the SeNPs group.
