ET: embryo transfer, good quality: embryos classified as grades I or II; poor quality: grades III or IV, mixed: when a grade I or II was transferred with a grade III or IV. D3: embryos transferred on third day of development, D5: embryos transferred on day 5. Values are n (%). †Chi-square test, ‡Fisher exact test. Patients with missing data were excluded from the analysis - study population delimited in n=.*Day 3 or Day 5 - day 2 and day 4 transfers were excluded from this analysis, ** only fresh transfer cycles included, *** excluded cycles using fresh embryos from frozen oocytes.
