Association between composite adverse perinatal outcome and absolute thresholds of umbilicocerebral ratio (UCR) or cerebroplacental ratio (CPR) assessed at inclusion, gestational age at measurement (GA), estimated fetal weight multiples of the median (EFW MoM) and pre‐eclampsia, in 856 pregnancies at risk of late‐onset preterm fetal growth restriction

Parameter	aOR (95% CI)	P
UCR < 0.7/CPR ≥ 1.43	—	< 0.001
UCR ≥ 0.7 to < 0.9/CPR ≥ 1.11 to < 1.43	1.6 (0.9–2.9)	0.10
UCR ≥ 0.9/CPR < 1.11	3.3 (1.7–6.4)	< 0.001
GA (in weeks)	0.8 (0.7–0.9)	0.03
EFW MoM	0.6 (0.4–0.7)	< 0.001
Pre‐eclampsia	2.0 (1.2–3.5)	0.01

Area under receiver‐operating‐characteristics curve of the model was 0.73 (95% CI, 0.67–0.78), with sensitivity of 70% and specificity of 64%.
