The Map of Evidence on Malnutrition and Interventions in Primary Health Care is a partnership between the General Coordination of Food and Nutrition of the Brazilian Ministry of Health (CGAN/DEPROS/SAPS/MS) and the Pan American Health Organization (PAHO/WHO). The Evidence Maps provide an overview of impact assessments and systematic reviews in a sector or area, which are mapped onto a framework by type of program evaluated (the intervention) and measured outcomes, graphically highlighting gaps, where few or no reviews or impact assessments exist, and where there is a concentration of evidence.
