From: The economic and personal burden of cluster headache: a controlled cross-sectional study
Flowchart of inclusion. Data presented for 400 patients with cluster headache. Means (SD) are based on the entire population, not only the patients receiving the specific healthcare service or social benefit. Underneath the cost the patients who received the service or benefit within the last year are indicated. The costs were not normally distributed, and we therefore applied the non-parametric Wilcoxon test. Some total costs do not total the sum of the means due to rounding
