Logarithm of MSAT ICER as a function of number of episodes in the comparator scenario. Costs and effects were discounted at an annual rate of 3% and aggregated over the eight years of the MSAT campaigns, using the US$7 MSAT cost estimate. The natural logarithm of the MSAT ICER was plotted against the number of episodes in the comparator scenario over the same time period, for each factorial combination averaged over 10 unique seeds. Colours indicate levels of case management coverage: Yellow: 0%, Pink: 20%, Blue: 35%, Black: 55%. Plotting characters indicate levels of ITN coverage: Squares: 0%, Stars: 40%, Circles: 60%, Triangles: 80%.
