Coefficients of the regression model for cerebral volumes and surface areas when accounting for age at scanning and sex differences as covariates

Dependent Variable^{^a}	Standardized Regression Coefficient (β)	Partial Correlation Coefficient (r)	T Statistics	Significance (2-Tailed)
Total cerebral volume (mm³)	0.066	0.072	0.712	.48
Cerebral WM volume (mm³)	0.148	0.130	1.271	.21
Cerebral cortex GM volume (mm³)	0.058	0.054	0.526	.60
Cerebral WM surface area (mm²)	0.148	0.130	1.271	.21
Cerebral cortex surface area (mm²)	0.098	0.089	0.865	.39
