Figure 1: Urinary concentrations of MiBP and MEHP [μg/L] according to the age groups. The lower and upper boundaries of the boxes represent the 25th and 75th percentile, respectively. The line within the box is the median level and the whiskers are the 5th and 95th percentiles. Spearman’s rank correlations [95% confidence interval] between metabolite concentrations and age are mentioned. ; ; .
