Impact and coverage levels of interventions.*

*MBP = Mother baby package; STI = sexually transmitted infection?Refers to whether direct or indirect evidence exists for the impact of the intervention on maternal mortality or morbidity. Evidence level is interpreted as follows for purposes of this analysis: A indicates that evidence comes from randomized controlled trial(s) conducted in a developed country setting, but the actual effectiveness of the intervention could be lower in developing countries due to reduced access and quality of care; B indicates that evidence comes from randomized controlled trial(s) conducted in a developed country setting, but actual intervention effectiveness is likely similar in developed and developing countries; C indicates that evidence is based on prospective cohort studies, observational and case control studies; D indicates an assumption is based solely on expert opinion; and none indicates an absence of evidence. The absence of evidence for an impact on mortality or morbidity is not intended to be interpreted as there is no effect, but indicates the absence of data to support an effect.?Provision of safe abortion is not a component of the MBP. Since the MBP strategy represents an upgrade from current practice patterns, however, coverage of safe abortion remains at the current practice level of 50%.
