Data are presented as rates (95% CI) adjusted for age (continuous), BMI (continuous), races (white, black, Asian, and others), and infertility diagnosis (male, female, and unexplained). A total of 100 fresh cycles were carried out among women who did not consume soy and 247 fresh cycles among women who consumed soy.
We classified embryos as best quality if they had 4 cells on day 2, 8 cells on day 3, and a morphologic quality score of 1 or 2 on days 2 and 3.
Tests for trend were performed using the median level of urinary BPA level in each group as a continuous variable in the model.
