O-PLS-DA comparison between plasma spectra from <i>K. pneumoniae</i> infected rats and corresponding controls and metabolite concentration changes relative to corresponding controls at different time points after <i>K. pneumoniae</i> infection.
<p>(A) Cross validated O-PLS-DA scores (left hand side) and coefficient plots (right hand side) generated from NMR spectral data of plasma of rats at 8 hours after <i>K. pneumoniae</i> infection (red dots), compared with those of non-infected (black squares). (B) a-c plots show metabolites changes in plasma. C<sub>inf</sub> and C<sub>con</sub> stand for the averaged concentration in the infection and control group, respectively.</p
