Specific fecal metabolites discriminate between control and NSAID-treated horses. A Heat map showing the distribution of the difference in fecal metabolites between day 10 and day 0 among the samples for the 50 most discriminative metabolites selected by MV-SIS. Values are scaled around zero as indicated by the key. Negative numbers (purple/blue) indicate lower concentration at day 10 compared to day 0 whereas positive numbers (orange/red) indicate higher concentration at day 10 compared to day 0. MGSDA-selected metabolites are shown in red text. B Bar chart indicating the magnitude of the loadings of MGSDA-selected metabolites. The misclassification rate (MCR) is indicated by the number at the top of each bar(s)
