  • a A threshold value indicates the value a variable would need to reach or exceed for removal of POIs to result in increased life-years. For example, in South Africa the maternal mortality ratio would need to decrease by 23% for the removal of POIs to be associated with increased life-years, assuming all other variables remain the same.

  • b Intrauterine device or implant.

  • c No threshold value exists; across all values of the maternal mortality ratio, removal of POIs results in loss of life-years.
