Medical Subject Headings (MeSH®) in MEDLINE®/PubMed®: A Tutorial
MeSH Tree Structures
Subheadings are arranged in logical hierarchical groupings (families). For example:
- therapeutic use
- administration & dosage
- adverse effects
A search of the subheading therapeutic use in PubMed would automatically explode to retrieve citations indexed with the subheadings administration & dosage, adverse effects, and poisoning.
Not all subheadings are placed in these groupings (as they do not logically fit).
