  1. Post hoc analysis with pairwise comparison of sub-groups according to Conover [14]. Data are shown as mean (±SD) and median (IQR)
  2. IQR inter-quartile range, MIG migraine, TTH tension-type headache
  3. 1No headache differs from both episodic headache and headache occurring on ≥15 days/month, without significant difference between the last two
  4. 2No headache differs from episodic headache, without significant difference between episodic headache and headache occurring on ≥15 days/month
