  1. Each step is in comparison with current conditions. YLS = Year or life saved.
  2. a In the model, age specific rates for use of contraception [13] were used in the national analysis, hence the average values are presented above. For the zonal analysis, average contraceptive rates were used and are presented above.
  3. b Cohort here is made up of the estimated number of women aged 15–45 years old. This amounts to 34.67 million nationally, 6.27 million in Southwest zone, and 3.95 million in the Northeast zone. National figures were derived from the UN World Population Projections [56], and the zonal figures from the 2006 census (here, the estimated proportion of women aged 15–45 years in each zone [18.5% and 11.7% in the Southwest and Northeast respectively] were applied to the UN World Population Projection). Additionally, negative costs imply cost savings. Results from the Northeast zonal analysis are in the supplemental text.
