In addition the number of paired samples for the Wilcoxon signed-rank test are depicted, as well as the resulting p-values. P < 0.0167 was considered as statistically significant after Bonferroni correction.
^*Abbreviations: trim = trimester; wkpp = weeks postpartum; GalNAc = N-acetylgalactosamine; Gal = galactose; SA = N-acetylneuraminic acid.
