Metabolomic profiles between infants diagnosed with LOS and matched controls across all 5 time points, where TP3 represents samples at diagnosis. a PCA (unconstrained ordination) of LOS infants (red) and matched controls (green). Each sample represented by the small circle and ellipses represent the 95% confidence interval. b Receiver operating characteristic curves of support vector machine predictions for LOS and control samples. AUC represents the strength of the predictive classifications. Selected number of metabolites computed in intervals from 5, 10, 15, 25, 50, and 100 metabolites
