Mixed effect model for the association of urinary BPA concentrations with peak oestradiol level, after adjusting for age, BMI and day 3 FSH levels and accounting for multiple IVF cycles
| Variable | Parameter estimate | 95% Confidence interval | p-value |
|---|---|---|---|
| Ln(SG-BPA) | −213 | (−407, −20) | 0.03 |
| Age | −7 | (−45, 31) | 0.71 |
| BMI | −20 | (−50, 9) | 0.17 |
| Day 3 FSH | −120 | (−185, −55) | 0.0004 |
Ln, natural logarithm; SG-BPA, specific gravity-adjusted bisphenol A; FSH, follicle-stimulating hormone; IVF, in vitro fertilization; BMI, body mass index.
