Self-rated health among patients with cluster headache and controls. Legend: Patients and controls were asked to rate their current health (N = 599). Patients in bout were defined as having a cluster headache attack within the last month. We dichotomized participants responding poor or very poor as poor and good or very good as good to increase power in an ordinal logistic regression adjusted for occupation and gender. Chronic cluster headache was the reference. Episodic cluster headache in bout were statistically indifferent to the chronic patients (OR 1.57, 95%CI 0.96–2.57, p = 0.074), The episodic cluster headache in remission were statistically different from the chronic patients (OR 3.22, 95%CI 1.90–5.47, p < 0.001), as were the controls (OR 10.10, 95%CI 5.29–18.79. p < 0.001)
