One-way sensitivity analysis results for cost per response of RCI versus PMP or IVIg

Treatment	Parametera	Uncertainty in parameter		Cost per response
		Lower estimate	Upper estimate	Lower bound	Upper bound
RCI	Total annual cost of care	US$107,462	US$139,816	US$124,090	US$161,450
	response rate	96.9%	78.3%	US$126,879	US$157,019
PMP or IVIg	Total annual cost of care	US$114,395	US$139,816	US$229,248	US$280,192
	response rate	56.0%	45.9%	US$225,736	US$275,407

IVIg, intravenous immunoglobulin; PMP, plasmapheresis; RCI, repository corticotropin injection.
