Comparison Between Scores of Pain and Health-Related Quality of Life of the Three Subgroups Based on the Pain Drawing

Patient Reported Outcomes	1 Headache with C2 Pain Pattern n = 116	2 Headache (no C2 Pain Pattern) n = 86	3 No Headache n = 73	P-value (Between Groups)
Pain intensity, VAS (0–100 mm) Median (IQR)	66.50 (49.00–79.00)	48.50 (31.00–65.25)	40.00 (19.00–57.00)	1–2 0.00 2–3 0.07
Body pain extent (0–100%) Median (IQR)	61.38 (44.62–76.31)	46.25 (28.19–64.31)	31.50 (15.50–51.00)	1–2 0.00 2–3 0.00
Health-related quality of life, EQ-VAS (0–100 mm) Median (IQR)	26.50 (20.00–38.25)	30.00 (20.00–40.00)	35.00 (25.00–50.00)	1–2 0.07 2–3 0.04
