Coefficient results of multivariate logistic regression models for prenatal HH including continuous variable and categorical variables with cut-points

Predicted Outcome	Predictor	β	SE	P
Prenatal HH (continuous variables)	IVH presence	1.6	1.1	1.6
	Right ventricular size by US (mm)	0.1	0.1	.08
	BPD (cm)	−3.6	1.5	.02^{^a}
	Head circumference (cm)	−1.1	0.4	.01^{^a}
	AUA	1.7	0.6	.003^{^a}
	Third ventricular diameter (mm)	2.5	0.7	<.001^{^a}
Prenatal HH (categoric variables with cut-points)	BPD (>4.5 cm)	−0.7	0.7	.34
	HC (>18 cm)	−1.2	0.7	.1
	AUA (>21 weeks)	0.6	0.7	.44
	Third ventricle diameter (>1 mm)	1.2	0.4	.001^{^a}

Note:—HH indicates hindbrain herniation; IVH, intraventricular hemorrhage; mm, millimeters; cm, centimeters; US, ultrasound; AUA, average ultrasound age; β, regression coefficient; SE, standard error.
↵a Significant difference P < .05.
