Positive correlation of illness duration and negative correlation of age of illness onset with FA

FA^a	Hemisphere	Talairach and Tournoux coordinates (peak voxel)			Peak Z score (ID/AO)	No. of voxels (ID/AO)	P
White matter tract/region		x	y	z
Anterior comissure/fornix	Inter-hemispheric	−3	−9	−3	3.79/3.92	90/105	< 0.001
Superior frontal white matter (next to dorsal cingulate gyrus)	Left	−16	−30	30	3.47/3.52	60/67	< 0.001
Superior and inferior longitudinal fasciculi	Right	38	−70	1	4.16/4.25	201/404	< 0.001

FA, fractional anisotropy; ID, illness duration; AO, age of illness onset

Fractional anisotropy increased with longer illness duration and earlier age of illness onset
