Figure 5. Assessment of the contribution of regions of the NMR spectra and specific metabolites to the discrimination between lens-induced and chronic uveitis. A: Loadings plots from the PLSDA analysis which indicates regions of the spectra which provide the greatest degree of discrimination between the two forms of uveitis. Positive peaks correspond to metabolites that are at higher concentration in the chronic relative to the LIU, and vice versa. B: Based on the original spectra and the loadings plot, peak heights of prominent metabolites resonances were plotted for each sample. Peak heights were compared using a T test.
