Descriptive Statistics (Mean and Standard Deviation) for the Low-Frequency and High-Frequency Hearing, MMSE, and Total GM Volume Measures.

	Low-frequency hearing	High-frequency hearing	MMSE	Total GM volume
Time 1	−0.24 (0.52)	−0.55 (0.90)	29.33 (0.76)	667.97 (77.61)
Time 2	−0.08 (0.68)	−0.43 (0.89)	29.07 (0.98)	658.56 (79.37)
Longitudinal change	*	**	ns	**

Note. Longitudinal change in each measure was estimated with paired-sample t tests. MMSE = Mini-Mental Status Examination; GM = gray matter; ns = not statistically significant.
