  1. 1Includes environmental phenols and other non-persistent consumer product chemicals. All studies included term, preterm, parous, and nulliparous births, and models of birth outcomes adjusted for or standardized to gestational age.
  2. 2Blank cells indicate associations were not examined; NS indicates that associations within that category were examined but not statistically significant at p<0.05.
  3. +Results only statistically significant among women with three urinary BPA measurements during pregnant (n=80)
  4. *Average of two or more urine samples.
