One-way sensitivity analysis (minimum values in order to be the most cost-effective option to control joint pain)

		Type of dominance
		Extended*	Absolute
Celecoxib
Control joint pain	↓	44.0%
Control joint pain without adverse events	↓	41.0%
Nonselective NSAIDs
Control joint pain	↑	67.5%	82.5%
Control joint pain without adverse events	↑	49.5%	63.0%
Acetaminophen
Control joint pain	↑	48.0%	55.0%
Control joint pain without adverse events	↑	94.0%	it is not feasible

NSAIDs, nonsteroidal anti-inflammatory drugs.

Extended dominance is defined as the set of all possible mixed therapeutic strategies that dominates a unique strategy in both higher effectiveness and less cost [67].
