From: Global host metabolic response to Plasmodium vivax infection: a 1H NMR based urinary metabonomic study

Figure 4

OPLS-DA scores plot showing the variation between urinary metabolic profiles of Plasmodium vivax- infected individuals and non-malarial fever patients. This model was constructed from 1H NMR data of urine from 21 P. vivax-infected individuals and 12 patients with non-malarial fever. All of the subjects were male. Each point in the plot represents one sample 1H NMR spectra. Black square = P. vivax- infected individual and red circle = non-malarial fever patients. The t[1] axis represents the predictive variation among the classes and the to[1] axis represents the variation orthogonal to the class specific variation. The statistical parameters of the model were as follows- R2X = 0.67 and Q2(cum) = 0.89. The ellipse is a 95% Hotelling's T2 ellipse.
