Fig 1 Cost-effectiveness in 2006 US dollars per patient achieving the DLQI MID, assessed over a 12-week treatment course. The slope from the graph origin to each point represents its cost-effectiveness compared with placebo; agents with similar slopes therefore have similar cost-effectiveness ratios. A smaller (lower) slope indicates a more cost-effective medication. Similarly, the slope between any two points in the graph represents the incremental cost-effectiveness ratio between those two medications. A vertical slope or negative slope of the line between medications indicates that the medication is less cost-effective. Agents with similar cost-effectiveness ratios (similar slopes), as determined by overlap in analysis of extreme scenarios at a level of variance of 5%, are shown in the same font in the figure (bold, italics, underlined, or regular). ALF, Alefacept 15 mg IM once weekly; ETN 25/wk, etanercept 25 mg SQ once weekly; ETN 25 2x/wk, etanercept 25 mg SQ twice weekly; ETN 50 2x/wk, etanercept 50 mg SQ twice weekly; ADA eow, adalimumab 40 mg SQ every other week; ADA qweek, adalimumab 40 mg SQ every week; INF 3mg/kg, infliximab 3 mg/kg IV for 3 infusions; INF 5mg/kg, infliximab 5 mg/kg IV for 3 infusions.

Fig 2 Cost-effectiveness in 2006 US dollars per patient achieving PASI-75 improvement, assessed over a 12-week treatment course. Similar to Fig 1, the slope of each line from the origin represents its cost-effectiveness compared to placebo. Also, the slope from any two points represents the incremental cost-effectiveness between the two agents. Agents with similar cost-effectiveness ratios (similar slopes), as determined by overlap in analysis of extreme scenarios at a level of variance of 5%, are shown in the same font in the figure (bold, italics, or regular). See Fig 1 for abbreviations. Journal of the American Academy of Dermatology 2008 58, 125-135DOI: (10.1016/j.jaad.2007.09.018) Copyright © 2008 American Academy of Dermatology, Inc.
