FRED uses the Index Medicus system for the database of Expertise terms. These terms are arranged in a hierarchical “tree” fashion that stems from 15 general terms. Child terms refer to more detailed “branches” of this tree structure, while Parent terms refer to the more general terms. To learn more about the Index Medicus system and the Medical Subject Heading (MeSH) terms, visit the NLM MeSH website.
