Fig. 8

Spearman correlation coefficients for non-targeted and targeted data. Correlation estimates are plotted for non-targeted metabolites using each normalization method and their conventional metabolite or targeted amino acid counterparts. Results are presented separately for each analytical sample type. All Spearman correlation estimates are statistically significantly different from 0 with p < 0.05 with the exception of tyrosine after EigenMS normalization in maternal fasting samples and methionine, glycerol, alanine and proline after Batch Normalizer in cord serum samples
