Drag the two red points around. They are the difference in suffering caused by intervention A and B respectively. The x axis is high-intensity pain, the y axis is low intensity pain

The green curve is the reduction of intervention A, relative to the reduction of intervention B, as a function of the weighting between high and low intensity pain along the x axis (e.g. x=1 is where the two pain intensities are equally bad)

The shaded orange regions are the "danger zones" (regions which, if D_B is in, will cause the ratio to blow up)

The dashed blue lines are the two extreme values of the green curve (the values that the green curve will take when x=1, and x=infinity)
