From: White matter changes in chronic and episodic migraine: a diffusion tensor imaging study
White matter alterations in chronic migraine compared to episodic migraine patients. TBSS shows decreased AD values in CM compared to EM in widespread locations with no covariate corrections (top) and correcting for time from onset of CM (bottom). White matter skeleton is shown in green, and voxels with significant differences in red-yellow. The colour bar shows the p-values (uncorrected). The maximum uncorrected p-value for each case is given by FDR and number of contrasts corrections
