  1. ART assisted reproductive technologies, CI confidence interval, ET embryo transfer, FET frozen-thaw ET, ICSI intracytoplasmic sperm injection, IVF in vitro fertilization, OR odds ratio
  2. aonly women who either achieved pregnancy or utilized all the embryos resulting from the index stimulation cycle were included in this analysis
  3. b only women who had one type of embryos transferred in both fresh and FET cycles, either only cleavage or only blastocysts, were included in this analysis
