Fig. 1From: Differences in gray matter volume in episodic migraine patients with and without prior diagnosis or clinical care: a cross-sectional studyCluster results showing region of reduced GMV in the right dorsal medial prefrontal cortex. The results are from a t-test of EM patients without prior clinical care compared to those with prior clinical care. A displays the cluster on the average brain created from all 117 patients. Cluster forming threshold of p=0.001, k=418, pFWE<0.05 at cluster-level. B displays the cluster on the SPM12 cortical surface. L: left; R: rightBack to article page
