Table 2.

Summary parameters for OPLS-DA models before and after treatment.

Groups Models R 2 X R 2 Y Q 2
LCI Before vs. after OPLS-DA 0.952 0.541 0.996
HCI Before vs. after OPLS-DA 0.951 0.682 0.994
MC Before vs. after OPLS-DA 0.850 0.622 1

R 2 X and R2Y show how well the model explains the variation in X and Y, respectively. Q2 represents the quality and predictive power of the model: values closer to 1 indicate a more stable and reliable model.
