Selected population
cycles: n 105 194   131 247  
POI (ng/ml/oocyte) 0.098 ± 0.064 0.100 ± 0.084 NS 0.105 ± 0.065d 0.107 ± 0.072b NS

  1. Legends: POI progesterone to oocyte index, P:E2 progesterone to estradiol ratio, PFI progesterone to follicle index, NS not significant
  2. Statistical analysis: The “p” column indicates the difference between pregnant and not pregnant women in cases of blastocyst or cleaved embryo transfer
  3. Difference between general and selected population (“top cycles”) for each index or ratio after blastocyst or cleaved embryo transfers: a-bp < 0.001, c-dp < 0.05
