      Note: We are updating the P4O model as new data become available. Thus, results produced may be different from results displayed in this table.

    • ↵a Assumptions: HR for HIV with DMPA=1.4; 75% of injectable users discontinue; 25% reallocate to other methods according to country-specific method mix after excluding permanent methods (sterilization); other parameters set to default.

    • ↵b Included sub-Saharan African countries: Botswana, Côte d'Ivoire, Ghana, Mozambique, Nigeria, South Sudan, Burundi, Ethiopia, Kenya, Lesotho, Liberia, Malawi, Namibia, Rwanda, South Africa, eSwatini, Tanzania, Uganda, Zambia, and Zimbabwe.

    • ↵c Other methods include emergency contraception, Lactational Amenorrhea Method, Standard Days Method, and other modern methods.
