Notes.
Model I: adjusted for age (smooth) and BMI.
Model II: The following confounders were adjusted: age (smooth), BMI, infertility duration, fertilization method, sterility classification, previous cycle attempts, basal FSH, basal LH, basal E2, FSH on hCG day, LH on hCG day, P on hCG day, endometrial thickness on hCG day, number of retrieved oocytes, the number of inviable embryos, and the number of embryos transferred.
