Reduced growth velocity across the third trimester is associated with placental insufficiency in fetuses born at a normal birthweight: a prospective cohort study

Table 3 Odds of placental insufficiency measures, per centile decrease in EFW/AC third trimester growth velocity

Outcome	Growth parameter	Odds ratio (95% CI) of outcome per centile decrease in third trimester growth velocity	P
CPR < 5th centile (n = 305)	EFW	1.024 (1.005–1.042)	0.01
CPR < 5th centile (n = 305)	AC	1.015 (0.997–1.032)	0.10
MCA PI < 5th centile (n = 308)	EFW	1.005 (0.987–1.025)	0.57
MCA PI < 5th centile (n = 308)	AC	1.013 (0.995–1.031)	0.17
UA pH < 7.15 at birth (n = 241)	EFW	1.024 (1.003–1.046)	0.02
UA pH < 7.15 at birth (n = 241)	AC	1.022 (1.002–1.041)	0.03
