Tornado diagram of the deterministic sensitivity analysis. This diagram shows a comparison of the costs of CBD treatment and usual care. Each bar represents a different cost-effectiveness ratio (ICER), clearly highlighting the strengths and weaknesses of the different treatment options. Blue bars represent cases where there were improvements in cost-effectiveness (e.g., cost reduction or effect increase). Red bars represent cases where there were higher costs or lower effects. C, cost; P, probability; response, response rate of the seizure-free; UC, usual care; CBD, cannabidiol
