Hierarchical regressions using neonatal hair cortisol levels as predictors of infant neurodevelopment.

		Cognitive	Receptive Language	Expressive Language	Fine Motor	Gross Motor
Neonatal hair cortisol levels	R 2	0.26	0.21	0.16	0.04	0.28
	β	0.13	−0.32	−0.04	−0.04	−0.31
	F	2.31	1.91	1.33	0.35	2.81
	p	0.41	0.07	0.27	0.87	0.03 **

Note: The model is adjusted for potential covariates (maternal level of education, salary, maternal age, and infant birth weight). ** p < 0.02.
