Sample Clinic Table of the 2008 ART Report
A comparison of clinic success rates may not be meaningful because patient medical characteristics and treatment approaches vary from clinic to clinic. For more details about this, along with information on how to interpret the statistics in this table read the introduction to fertility clinic tables.

a— Reflects patient and treatment characteristics of ART cycles performed in 2008 using fresh nondonor 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 women of this age group (see Figure 16, Figure 34, and Figure 43).
e— All ages (including ages >44) are reported together because previous data show that patient age does not materially affect success with donor eggs.
