In cost-effectiveness analysis, a case in which an alternative or treatment can be ruled out because it would not be cost-effective at any cost-effectiveness threshold. Strong dominance applies when the alternative is both more effective and less costly than at least one other alternative. Weak dominance (also known as extended dominance) applies when an alternative is less costly than another, but has a higher incremental cost-effectiveness ratio.
