  1. Values are expressed as mean (SD). The p values were calculated using appropriate statistical tests (2-tailed paired t test or 2-sample t test for continuous data and χ2 tests for categorical data)
  2. ETTH episodic tension-type headache, SAS self-rating anxiety scale, SDS self-rating depression scale, VAS visual analog scale
  3. *2-tailed paired t test for SAS or SDS scores between pain phase and out of phase in ETTH patients
  4. **2-sample t test for SAS or SDS scores between ETTH patients in pain phase and healthy controls
  5. ***2-sample t test for SAS or SDS scores between ETTH patients out of pain phase and healthy controls
