Scatter-plot showing the distribution of characteristic metabolite levels in affected and unaffected amniotic fluids. a The distribution of C3 levels in AFs between affected and unaffected samples; b the distribution of C3/C2 ratios in AFs between affected and unaffected samples; c the distribution of 2MCA levels in AFs between affected and unaffected samples; d the distribution of 3HPA in AFs between affected and unaffected samples. Horizontal lines, median values. P values were determined by the Wilcoxon rank sum test, *P < 0.05, ** P < 0.01, *** P < 0.001
