* Beta values represent the grey matter volume in the right dorsal medial prefrontal cortex in mm³. All models are adjusted for age; it was correlated with disease duration and was a better predictor in the model; REF reference level for comparison, DMPFC dorsal medial prefrontal cortex, EM episodic migraine, GMV Gray Matter Volume
