Generalized Linear Regression Model Results for Other NICU Outcomes, N = 319

	Model 1			Model 2
	RR (95% CI)	Average Marginal Effect^*	p-value	RR (95% CI)	Average Marginal Effect^*	p-value
Outcome: NICU Length of Stay
DM feeding era	0.95 (0.88 – 1.01)	−4.8 ± 1.9	0.110	0.93 (0.88 – 0.99)	−5.8 ± 2.4	0.031
Outcome: Cost per Day
DM feeding era	0.99 (0.97 – 1.00)	−24±1	0.274	1.00 (0.98 – 1.01)	−4.9 ± 0.3	0.800

Model 1 adjusts for neonatal risk factors (GA, birth SGA, surfactant), sociodemographic risk factors (race/ethnicity, sex, payer) and DOL of the first feeding. Model 2 also adjusts for the presence of morbidities.
