Table 2

Relationship of fetal response to spontaneous onset of labour and unexplained fetal death.

	Fetal response 𝑛=96 (%)	Absence of fetal response 𝑛=856 (%)	Unadjusted odds ratio (95% CI)	Adjusted odds ratio* (95% CI)	P value
Spontaneous onset of labour (𝑛=303/952)	65 (67%)	238 (27%)	5.4 (3.5–8.6)	4.4 (2.7–7.2)	< 0.0001
Unexplained death (𝑛=469/952)	15 (16%)	454 (53%)	6.1 (3.5–10.7)	4.5 (2.4 – 8.4)	<0.0001

*Adjusted for: fetal growth restriction < 10th percentile, bleeding during pregnancy, maternal medical conditions, maternal hypertension, fetal or maternal proven infection, and gestational age.
