  1. Adjusted for maternal age, fertilization method, type of ovarian stimulation and paternal BMI and age
  2. Significant differences are depicted in bold
  3. CI Confidence interval
  4. aIn cases of regular IVF, embryos are only transferred to the EmbryoScope after PN inspection, thus tPNa cannot be observed
