Prediction of Adverse Pregnancy Outcomes Using Crown‐Rump Length at 11 to 13 + 6 Weeks of Gestation

To assess the risk of a fetus with a smaller or larger than expected crown-rump length (CRL) for adverse pregnancy outcomes.The data of 960 healthy singleton pregnancies conceived via in vitro fertilization were retrospectively collected. Fetal CRL was measured between 11 and 13 + 6 weeks of gestation, and small and large fetal CRLs were defined as fetuses below the 10th and above the 90th centiles, respectively.
