  1. Statistically significant results comparing a specific category to the reference are bolded
  2. 1Serum AMH levels were natural logarithm transformed
  3. 2Phthalate metabolite concentrations were categorized into quartiles
  4. 3Dichotomous variable based on above/below limits of detection
  5. 4Model 1 was adjusted for age, BMI and creatinine
  6. 5Model 2 was adjusted for age, BMI, creatinine and PCO/PCOS diagnosis (yes or no)
  7. 6Reference category
