Somatosensory gray matter is independently related to pain, anxiety, and urgency SYM-Q scores.

Dependent Variable	Predictors	Standardized Beta	S.E. Unstandardized	p-Value	R Square Full Model
Right S1 GM Volume					0.53
	Age	−0.15	0.001	0.225
	Pain (SF-MPQ sensory)	0.30	0.001	0.01
	Anxiety (HADS)	0.50	0.002	0.008
	Urgency	0.44	0.002	0.004

A linear regression model was constructed with the gray matter ROI in the right primary somatosensory cortex as the dependent variable and age, pain sensory, anxiety, and urgency as predictors. The total model explains approximately 53% of the variance in GM values. S1=primary somatosensory cortex, GM=gray matter
