Fig. 4

The visualization of brain regions with significant differences in cerebral perfusion between NDPH and HC groups, CM and HC groups, as well as NDPH and CM groups. The brain regions with decreased cerebral perfusion in NDPH groups were presented compared with HC (A) and CM (B) groups, respectively. The brain regions with increased cerebral perfusion in CM groups were presented compared with HC groups (C). HC healthy control, NDPH new daily persistent headache, CM chronic migraine.
