Table 4 Parameters for OPLS-DA models derived from ¹H-NMR spectra of plasma samples from controls and micro and SD patients

* R² and Q² intercept values are indicative of a valid model. The permutation test was evaluated on the corresponding partial least square discriminant analysis (PLS-DA) model
^a Number of predictive and orthogonal components used to create the statistical models
^b,c R²X and R²Y indicate the cumulative explained fraction of the variation of the X block and Y block for the extracted components
^d Q²cum values indicate the cumulative predicted fraction of the variation of the Y block for the extracted components
