O-PLS-DA model summary for discriminating NMR spectra of plasma, urine, liver and ileal flushes
| Discrimination analyzed/sample | Conventional versus re-conventionalized | Conventional versus HBF |
|---|---|---|
| Plasma | Q2Y=29%, R2X=23% | Q2Y=70%, R2X=28% |
| Urine | Q2Y=40%, R2X=37% | Q2Y=75%, R2X=44% |
| Liver | Q2Y=42%, R2X=54% | Q2Y=46%, R2X=54% |
| Ileal flushes | Q2Y <0 | Q2Y=35%, R2X=84% |
O-PLS models were generated with (1) predictive component and (2) orthogonal components to discriminate between two groups of mice. The R2X value shows how much of the variation in the data set X is explained by the model. The Q2Y value represents the predictability of the models and relates to its statistical validity. A negative value indicates that differences between groups are statistically nonsignificant.
