Only singleton fetuses with an unremarkable pregnancy outcome were included in this study. The repeated NT either at a threshold of &gt;2.5 mm or \u2a7e95th centile of the normal range for various CRLs (2 mm at a CRL \u2a7d44 mm to 2.85 mm at CRLs 83\u201384 mm) was assessed.

The relative risk of an isolated NT \u2a7e2.5 mm in the first pregnancy to be followed by a similar finding in the subsequent one was 18.21 (95% confidence interval [CI]: 3.62\u201391.55).
