These supplementary files detail the definitions, calculations, assumptions, limitations, and sources used to identify parameters for the RACE-FP decision support tool developed for family planning (FP) policy makers in the Philippines. The objective of RACE-FP (Reach Health Assessing Cost-Effectiveness for Family Planning) is to estimate the impact single or combined FP interventions have on averting unintended pregnancies at national and regional levels and on downstream maternal and neonatal health (MNH) related outcomes. A secondary RACE-FP objective is to estimate intervention and supply costs to inform key decision makers how to best allocate limited resources to achieve FP-related goals. There are six total supplements that are referenced throughout the RACE-FP methodology report (published elsewhere) that convey the technical details of the model. This upload includes Supplements A-F as well as the references cited throughout: Supplement A. Model Population Supplement B. Contraceptive Penetration, Utilization, and Effectiveness Supplement C. Contraceptive Commodity Costs Supplement D. Intervention Parameters Supplement E. RACE-FP Outcomes Supplement F. Model Sensitivity Results, {"references":["1.\tPhilippine Statistics Authority (PSA).
