PCA scores plot showing the variation between urinary metabolic profiles of Plasmodium vivax- infected individuals and non-malarial fever patients. The PCA scores plot demonstrates that the infection by the parasite brings in considerable variation in the urine profile of the individuals. Here the variation is seen along PC2. This PCA model was constructed from ¹H NMR of 21 patients with P. vivax infection and 12 patients with non-malarial fever. All of the patients were male. Each point represents one sample ¹H NMR urine profile. Black square = P. vivax- infected individuals and red circles = non-malarial fever patients. R²X for the model = 0.67.
