Figure 3. Two-way sensitivity analysis strategy graph comparing adherence for isoniazid/rifapentine daily for one month (1HP) vs. isoniazid/rifapentine weekly for three months self-administered (3HP-SAT).

In the diagonal cross-hatched area, 1HP is cost-saving and therefore the preferred regimen. In the horizontal cross-hatched area, 3HP-SAT is cost-saving. In the shaded area, neither regimen is cost-saving when compared to isoniazid monotherapy daily for nine months (9H), which is the preferred regimen.
