An intervention is more expensive and less effective than the comparison. How is it classified?

Explanation:
In cost-effectiveness analysis, the key idea is to compare both costs and outcomes. When an intervention costs more and yields less health benefit than the alternative, it is dominated by the comparator. This means there’s no scenario where choosing the intervention is preferable, since you pay more and get worse results. The term for this is strictly dominated. The other options don’t fit: being dominant would mean it’s cheaper and more effective, time horizon issues or indirect costs can influence results but don’t classify the intervention here.
