Pairwise Spearman correlation values for maternal and newborn QC samples in HAPO Metabolomics prior to and following normalization with each approach. Points correspond to the mean pairwise Spearman correlation value and lines span the minimum to the maximum pairwise Spearman correlation for each sample type. All Spearman correlation estimates are statistically significantly different from 0 with p < 0.05
