MPCA scores plot based on CPMG 1H NMR spectra of sera and pleural effusion of C57BL/6 mice with CM on PC 2 and MPCA loadings plot of CPMG 1H NMR of sera and pleural effusion of CM C57BL/6 mice. The numbers assigned to the peaks corresponds to the numbers in Figure 2. (A) Each blue dot represents score of a CM mouse (considering sera and pleural effusion together) on PC2 in a MPCA plot. (B) Loadings line plot of sera and (C) pleural effusion of CM mice on PC2 of MPCA. The opposite direction of the signals bears a meaning of anticorrelations among the corresponding metabolites whereas similar direction of the signals indicates positive correlation among the metabolites.
