Results of univariate sensitivity analysis. The tornadogram shows selected results of univariate sensitivity analysis for PCV9. The x-axis represents the range of the incremental cost-effectiveness ratios for vaccination using PCV7 when the base-case assumptions were varied over plausible ranges (as shown in the brackets). The vertical line represents the base case cost-effectiveness ratio of PCV7, $910 per DALY averted.
