Serum total adiponectin (T-ADP) and ADP multimers in non-diabetic, normotensive reproductive-aged (<50) women with episodic migraine (EM, n = 13), chronic daily headache (CDH) with either chronic or transformed migraine (n = 12), and non-headache controls (n = 12). After adjusting for WHR, levels varied significantly across the three headache groups (P = .024). Adapted from Ref. 39.
