Figure 1

Heat map of urinary metabolites which significantly differ (P < .05) between children in the highest quintile (Q5) and those in the lowest quintile (Q1) groups of urinary propyl-paraben. Significantly different metabolites between the two groups are presented according to the amino acid, lipid, and carbohydrate metabolites. CHO, carbohydrate; Q1, lowest quintile group of urinary propyl-paraben; Q5, highest quintile group of urinary propyl-paraben.
