Multiple logistic regression for the different Doppler measurements

Parameters	B value adjusted odds ratio with 95% CI	P value
MCA PI <5th centile	−0.005 (−0.205 to 0.196)	.963
High UA PI	0.032 (−0.257 to 0.321)	.826
Absent UA	0.624 (0.327–0.920)	.000
Reversal UA	0.514 (0.015–1.012)	.043
CPR <5th centile	0.040 (−0.231 to 0.311)	.771
Abnormal DV	−0.051 (−0.391 to 0.290)	.769
Abnormal AoI	−0.027 (−0.266 to 0.212)	.824
