A Two-dimensional principal component analysis score plots. B Partial least-squares discriminant analysis (PLS-DA) score plots for principal components 1 and 2. The control group is represented by yellow circles, and the intrauterine growth restriction group is represented by green circles. C Compounds represented in the variable importance in projection scores are numbered according to their ranking in false discovery rate correction for univariate analysis. The 15 compounds that contributed most to group separation, as identified through PLS-DA and ranked by variable importance in projection scores. The heatmap on the right shows the mean intensity in the respective groups, with red and blue indicating high and low metabolite levels, respectively (n = 6)
