Figure 3. Partial least squares discriminant analysis (PLS-DA) of vitreous fluid NMR spectra from lens-induced uveitis and chronic uveitis patients. A PLS-DA model was constructed to predict diagnostic groups. A: Latent variable plot of the PLS-DA model, showing improved discrimination between LIU and chronic uveitis compared with the PCA analysis (Figure 2). B: Prediction of the group membership from the PLSDA. The model was cross validated, and was able to predict the classes, LIU and chronic uveitis, with sensitivity of 78% and specificity of 85%.
