Table 3

Table 3. Morphology and outcome, as well as distribution of embryos, split by day of transfer. Day-5 and day-6 blastocysts are grouped together. For each morphological class, the data is presented as PR, CPR and LBR (in bold). For each category, the contribution of each KIDScore class is presented as percentage (in italics)
