Area under the curve of the receiver operating characteristic curve for secondary neonatal outcomes

	Individualized standard	Population standard	P*
RDS	0.52 (0.49 – 0.55)	0.43 (0.40 – 0.46)	<.001
Necrotizing enterocolitis	0.54 (0.49 – 0.58)	0.49 (0.45 – 0.54)	<.001
IVH, grade 3 or 4	0.44 (0.34 – 0.54)	0.38 (0.26 – 0.49)	0.04
ROP	0.56 (0.53 – 0.60)	0.48 (0.45 – 0.52)	<.001
Seizures	0.55 (0.46 – 0.64)	0.51 (0.40 – 0.61)	0.15
Sepsis	0.57 (0.54 – 0.61)	0.52 (0.49 – 0.56)	<.001

RDS = respiratory distress syndrome; IVH = intraventricular hemorrhage; ROP = retinopathy of prematurity
