Outcomes of single vitrified-warmed blastocyst transfer cycles according to the degree of post-warming embryo re-expansion
Collapsed (n = 70) | Partial re-expansion < 50% (n = 103) | Partial re-expansion ≥ 50% (n = 156) | Full re-expansion (n = 283) | Unadjusted p value | |

Positive hCG | 14 (20.0) a | 32 (31.1) a, b | 61 (39.1) b | 164 (58.0) | < 0.001 |
Clinical pregnancy | 8 (11.4) a | 18 (17.5) a, b | 43 (27.6) b | 127 (44.9) | < 0.001 |
Miscarriage | 1 (1.4) | 8 (7.8) | 6 (3.8) | 23 (8.1) | 0.09 |
Live birth | 8 (11.4) a | 15 (14.6) a | 40 (25.6) a | 110 (38.9) | < 0.001 |
