Heatmap of the 20 metabolites with the highest Hotelling’s T² value. Heatmap of changes in breast milk metabolites at 6 weeks (purple) and 6 months (yellow) postpartum between mothers with (red) and without HIV (blue). The heatmap was created using the statistical package in MetaboAnalyst 5.0 (http://www.metaboanalyst.ca/MetaboAnalyst/). The heatmap is a visualization of the changes in abundance/level of breast milk metabolites (rows) for each mother (columns). The color ranges from dark red (high abundance or level) to dark blue (low abundance or level); white is no change
