a) Reflects patient and treatment characteristics of ART cycles performed in 2013 using fresh, non-donor eggs or embryos.
b) When fewer than 20 cycles are reported in an age category, rates are shown as a fraction and confidence intervals are not given. Calculating percentages from fractions may be misleading and is not encouraged.
c) A multiple infant birth is counted as one live birth.
d) Clinic-specific outcome rates for women older than 44 undergoing ART cycles using fresh or frozen embryos with nondonor eggs are not included because of small numbers. Readers are urged to review national outcomes for these age groups.
e) All ages (including ages >44) are reported together because previous data show that patient age does not materially affect success with donor eggs.
The above information was submitted to SART (Society for Reproductive Technology) in December, 2014 and are included in the 2013 national report as well as the Centers for Disease Control and Prevention (CDC) 2013 ART statistics.
Research cycles are included in SART data, not in CDC data, thus you will notice a difference in the SART and CDC data reports.
