SET=Single embryo transfer, DET=Double embryo transfer, CI= confidence interval.
* adjusted model controls for age; a Not applicable to all patients, because of no embryo transfer in 13 patients, (endometriosis), 15 patients (other); b Morphology score 1-best, 4-worst. Morphology score performed on day 2; c The pregnancy test was performed two weeks after ET. Missing values: 1 (endometriosis); d Defined as pregnancy ≥ 12 weeks. Missing values: 2 (endometriosis), 4 (other).
