Probabilities (mean ± standard error) of membership to FM groups for patients included in headache types (CM chronic migraine, MA migraine with aura, MWA migraine without aura, CTH chronic tension-type headache, ETH episodic tension-type headache, HC hemicrania continua, HP paroxysmal hemicrania), according to the discriminating function. The results of Bonferroni test, revealed that CM and CTH groups significantly differed from the others (p < 0.01), for the highest probability to share the FM profile, while MA differed from the others for the lowest probability (p < 0.05)
