Table 4:

Incremental Cost Effectiveness

Base Case, cost per quality adjusted life year (QALY) using intervention replication cost, total medical care cost
	Cost	Incremental cost	QALY	Incremental QALY	ICER
Control group	$25,506		0.5459
Treatment group	$23,665	−1841	0.5695	0.0236	Intervention Dominant
Cost-effectiveness plane quadrant results: SE 80%; NW 0%; NE 20%; SW 0%

Dominant means the intervention had lower costs and greater effect

Supplemental analysis difference from base-case shown in italics

Cost-effectiveness plane quadrant results legend:

SE=intervention was less costly and more effective; always cost-effective

NW=intervention was more costly and less effective; never cost-effective

NE=intervention was more costly and more effective; cost-effective depending on willingness-to-pay for a unit of effectiveness

SW=intervention was less costly and less effective; cost-effective depending on willingness-to-pay for a unit of effectiveness

All analyses adjusted for baseline cost and baseline outcome measure
