Figure 2. One-way sensitivity analyses: effect of parameter variation on the ICER.

Figure 2

All model parameters were varied and those with the highest relative effect on ICER are displayed. Dark-shaded bars represent the lower bound of variable range. Light-shaded bars represent the upper bound. The first number listed after the variable name is the base case value. Numbers listed in parentheses indicate the range over which the value was varied in the sensitivity analysis. Baseline incremental cost per QALY is ~$22,000. IV tPA indicates intravenous tissue plasminogen activator; mRS, modified Rankin Scale; QALY, quality-adjusted life-year.
