Serum metabolite profile in early pregnancy. A PLS-DA plot shows separation between groups; control (blue circles) and gestational diabetes mellitus (red circles). The explained variances are shown in brackets (PC1 (69.2%) and PC2 (13.9%; accuracy: 0.83, R2 = 0.42, and Q2 = 0.28: permutation p-value = 0.13); B Hierarchical heatmap, red and green, indicate increase and decreased concentration, respectively
