Influence of PHS on Neurodevelopmental Outcomes in Regression Models

Outcome	Model 1: Demographics		Model 2: Demographics + Morbidities
Outcome	Mean Diff/OR (CI)	p-value	Mean Diff/OR (CI)	p-value
Bayley III cognitive score	2.38 (0.54, 5.61)	0.018	2.47 (−0.01, 5.04)	0.06
Bayley III motor score	5.1 (2.39, 7.81)	<0.001	4.65 (1.93, 7.38)	<0.001
GMFCS level 2+	0.62 (0.35, 1.10)	0.104	0.61 (0.33, 1.13)	0.117
NDI (cognitive score < 70)	0.60 (0.38, 0.94)	0.026	0.5 (0.39, 1.02)	0.058
NDI (cognitive score < 85)	0.73 (0.50, 1.08)	0.114	0.77 (0.51, 1.15)	0.199

Model 1 variables: GA at birth, sex, race/ethnicity, maternal education, PMA at status, SGA, HC z-score at birth

Model 2 variables: Model 1 + sepsis, NEC, IVH grade 3–4/PVL, postnatal steroids, BPD

Both models also controlled for clustering by center
