Regression models for the effect of age, hippocampal volume, and hippocampal NAA/Cr on stride length in older adults.

	Predictors	R2	Standardized Beta	p-value
Model 1	Age	0.33	−0.33	0.04*
	Midsagittal Area		0.03	0.83
	Hippocampal Volume		0.36	0.03*
Model 2	Age	0.28	−0.49	0.00**
	Hippocampal NAA/Cr		0.09	0.48
Model 3	Age	0.35	−0.33	0.04*
	Midsagittal Area		0.05	0.73
	Hippocampal Volume		0.42	0.02*

^*Significant at the p<0.05 level.

^**Significant at the p<0.01 level.

Note: NAA/Cr=N-acetylaspartate/creatine ratio.
