rFPN resting state functional connectivity (rs-fc) results. 4A. MwoA showed reduced rFPN rs-fc with the precuneus at baseline compared with HC; 4B. fFPN rs-fc between the precuneus and MPFC/rACC was associated with headache VAS at baseline; 4C. The reduced rFPN rs-fc with the precuneus due to acupuncture treatment (verum + sham); 4D. The greater reduction of rFPN rs-fc with the right precuneus was associated with greater headache intensity relief. A threshold of Z > 2.3, P < 0.05 was applied. AG, acupuncture groups; HC, healthy controls; MwoA, migraine without aura; R, right side; rFPN, right frontoparietal network; VAS, visual analogue scale.
