Main effects of independent variables on cortical thickness in 66 Freesurfer ROIs; results of a linear mixed model analysis

Main effect	P value	Beta value [95% CI]
ROI	<  0.001	a [ a ]
Age (covariate)	0.002	−0.006 [(− 0.01)-(− 0.002)]
Stenosis = no (no stenosis > stenosis)	0.180	0.009 [(− 0.004)-0.023]
Group = patients (patients < controls)	0.796	−0.009 [(− 0.08)-0.062]
Hemisphere = right (right < left)	0.937	−0.0004 [(− 0.01)-0.009]
