Fig. 3From: The influence of maternal prepregnancy weight and gestational weight gain on the umbilical cord blood metabolome: a case–control studyClustering heat maps of differential cord blood metabolites of the three groups. A positive metabolites; B negative metabolites. Notes: Longitudinal clustering of samples and trans-verse clustering of metabolites. The shorter the clustering branches, the higher the similarity. Through horizontal comparison, we can see the relationship between groups of metabolite content clusteringBack to article page
