Table 7 Response variables for the entire population and subgroup having good/fair quality embryos transferred on day 5

From: In high responding patients undergoing an initial IVF cycle, elevated estradiol on the day of hCG has no effect on live birth rate

  1. All values are Mean ± 1SD.
  2. Differences within row comparing the same response variable by pregnancy status (NLB or LB) for the entire population or patients having only good or fair quality embryos transferred having the same superscript are different; ap <0.001; bp < 0.010, cp < 0.007, dp <0.040.
  3. *Chi Square comparison for difference between Day 3 and Day 5 in the total population for Live Birth was p < 0.02.
  4. **Chi Square comparison for difference between Day 3 and Day 5 in populations with only good or fair quality embryos used for transfer was NS.
