TMA and one of its main precursors, TMAO, are driving the separation between UTI-positive and negative samples in multivariate analysis. (A) Principal components analysis (PCA) score plot of Healthy (black, n = 10) vs UTI-positive samples (red, n = 15), where each point represents a single sample from a single woman. The location of each point displays differences in the metabolome, with samples closer to each other being similar. Ellipses represent the 95% confidence intervals; (B) PCA loadings, which show the weights of each metabolite in the principal component cartesian plane. Each point represents a single metabolite. Biogenic amines, as well as their precursors, are colour coded.
