  1. *p < 0.05 between CM and controls; **p < 0.05 between EM and controls; there are no statistical differences between CM and EM for PREP parameters. P-values were determined using the Mann–Whitney U test. All values are expressed as means and standard deviations
  2. EM episodic migraine, CM chronic migraine, PREP pain-related evoked potential, PPA peak-to-peak amplitude, AUC area under the curve
