  "term": "Key study",
  "field": "Environment",
  "definition": "A study that is the most up-to-date and scientifically sound for deriving recommendations for exposure factors. Alternatively, studies may be classified as \"relevant\" and not \"key\" for one or more of the following: (1) they provide supporting data (e.g., older studies on food intake that may be useful for trend analysis); (2) they provide information related to the factor of interest (e.g., data on prevalence of breast feeding); or (3) the study design or approach makes the data less applicable for exposure assessment purposes (e.g., studies with small sample size, studies not conducted in the United States). As new data or analyses are published, \"key\" studies may be moved to the \"relevant\" category because they are replaced by more up-to-date data or an analysis of improved quality.",
