This table shows the characteristics of the study sample. Statistical analysis aimed to assess for statistically significant differences regarding sex, age, body mass index (BMI), number of myofascial trigger points (mTrPs), medication intake (analgesic drugs, days/month), headache (days/month), and neck pain (number of subjects with neck pain) in subjects with tension-type headache only (TTH-), TTH plus migraine episodes (TTH+), and healthy controls (HC). Values are given as absolute numbers or percentages, mean values ± standard deviation (SD), and/or ranges
