Erratum: Braun et al. “Variability of Urinary Phthalate Metabolite and Bisphenol A Concentrations before and during Pregnancy” [120:739–745 (2012)]

Braun et al. discovered an error in the SAS code of their paper “Variability of Urinary Phthalate Metabolite and Bisphenol A Concentrations before and during Pregnancy” [Environ Health Perspect 120:739–745 (2012)]. The error resulted in the reported absolute concentrations of phthalate metabolites and BPA being approximately 50% higher. The authors mistakenly used the median value from the EARTH study men [specific gravity (SG) = 1.025] rather than women (SG = 1.015) in their SG calculations. Thus, the reported concentrations in Table 2 (columns 2 and 3), Table 4 (columns 2 and 3), and Figure 1, as well as in the Supplemental Material, were higher than if the median SG for this group of women had been used. The authors note that this error did not alter the statistical analyses or their interpretations or the conclusions of their paper. The authors regret the errors.
