Changes in regional homogeneity in patients with migraine without aura and healthy controls during the study period.

(A) Difference in ReHo between MwoA and HCs
Contrast	Brain region	MNI (x, y, z)			T-value	Voxels
PM < HC	Right cerebellum	18	−60	−42	4.4607	131
	Left cerebellum	−18	−63	−42	4.9429	102
(B) Changes in ReHo in different stages of treatment
Contrast	Brain region	MNI (x, y, z)			F-value	Voxels
PMa-PMb-PMc	Left cerebellum	−9	−36	−30	3.805	20
	Left angular gyrus	−60	−63	27	3.7857	23
(B1) Changes in ReHo in different stages (post-hoc analysis)
Contrast	Brain region	MNI (x, y, z)			T-value	Voxels
PMb > PMa	Left cerebellum	−12	−33	−33	4.7578	20
(B2) Changes in ReHo in different stages (post-hoc analysis)
Contrast	Brain region	MNI (x, y, z)			T-value	Voxels
PMc > PMa	Left angular gyrus	−57	−57	24	4.848	23
(B3) Changes in ReHo in different stages (post-hoc analysis)
Contrast	Brain region	MNI (x, y, z)			T-value	Voxels

(A) Comparison of ReHo between patients with MwoA and HCs. (B) Changes in ReHo in different periods of acupuncture treatment (P < 0.001, GRF, cluster P < 0.05, cluster >20). (B1) Changes in ReHo between before and after first acupuncture session (FWE, P < 0.05). (B2) Changes in ReHo between before and after acupuncture (FWE, P < 0.05). (B3) Changes in ReHo between after first acupuncture session and after 12th acupuncture session (FWE, P < 0.05). FWE, family-wise error; HCs, healthy controls; MwoA, migraine without aura; ReHo, regional homogeneity; PM, patients with migraine; PMa, before acupuncture; PMb, after first acupuncture session; PMc, after 12th acupuncture session.
