Cluster 1 N= 232, cluster 2 N= 318, cluster 3 N= 201

Cluster 1 is the reference cluster.

Cluster1 was characterized by the lowest biomarker concentrations, except for BPS. Cluster 2 was characterized by the highest concentrations of the parabens, two phenols (BPF and triclosan), metabolites of low molecular weight phthalates, and one metabolite of high molecular weight phthalates (MBzP). Cluster 3 was characterized by the highest concentrations for metabolites of high molecular weight phthalates (except MBzP), triclocarban, and most phenols.
