ROI	rCBVR		ΔTTFM, seconds
	Before Intervention	After Intervention	Before Intervention	After Intervention
PCAT	0.98 ± 0.17	0.96 ± 0.26	−0.14 ± 0.42	−0.02 ± 0.68
MCAT1	1.01 ± 0.19	0.91 ± 0.18	1.31 ± 1.15*	0.51 ± 0.61†‡
MCAT2	1.06 ± 0.27	1.00 ± 0.13	1.09 ± 0.90*	0.57 ± 0.75†
ACAT	1.11 ± 0.36	1.01 ± 0.51	0.12 ± 0.64	0.16 ± 0.66

Note.—Data are the mean ± standard deviation. For cases of inter-hemispheric symmetry, the rCBV_R was 1, and ΔTT_FM was 0 seconds.

^*Statistically significant interhemispheric asymmetry in mean TT_FM, P < .005.

^†Statistically significant interhemispheric asymmetry in mean TT_FM, P < .05.

^‡Significant difference in mean ΔTT_FM before and after intervention, P < .05.
