Reverse Kaplan-Meier curves for time to mitosis resumption and time to compaction after thawing/warming of human cryopreserved embryos in dataset 2. The groups of vitrified and slow frozen embryos, of intact and not intact embryos and of implanted and non-implanted embryos were compared for both morphokinetic characteristics. Clustered log rank test p-values indicated a significantly faster mitosis resumption (p = 0.0185) and faster compaction (p = 0.0001) in vitrified embryos compared to slow frozen, and significantly faster mitosis resumption in intact embryos compared to not intact (p = 0.03). All other comparissons showed no significant differences
