The inter-individual variation in fatty acid profiles changes with postnatal age
We used Uniform Manifold Approximation and Projection (UMAP) to reduce the dimensionality of the data and compare individuals’ complete fatty acid profiles (Cord blood and day 1 samples clustered together while samples collected from postnatal day 3 to postnatal week 4 displayed higher heterogeneity; the latter was especially true for when the fatty acid content was expressed as absolute serum concentration. Samples from week 6 to week 12 formed a relatively cohesive cluster in both data sets (relative and absolute).
