All values were varied ±25 % in sensitivity analysis using a gamma distribution, with the exception of those marked ^a or ^b. Where this variation exceeded the maximum plausible value, the maximum/minimum limit was used. ^aValue was varied in sensitivity analysis based on data reported in the source (0.00, 253.95). ^bValue was varied in sensitivity analysis based on data reported in the source (0.00, 369.75). ^cThe cost applied to combination therapy was adjusted to 80 % of this value as DFO was assumed to be given four times weekly
