Relationship Relationship Attribute Count (MRREL.RRF)
SY has_alias 36400
SY has_expanded_form 31210


Sample data are taken from MRREL.RRF. Associated strings(str) from MRCONSO.RRF are also included

  • See relationships definitions below.
  • Every relationship has a separate row in MRREL.RRF.
  • Relationships are assigned based on source documentation or NLM understanding of the source.
  • Metathesaurus relationships in MRREL.RRF are read from right to left.
  • All relationships in MRREL.RRF are expressed in both directions, for example: 'has_ingredient/ingredient_of'. Inverse relationships in each pair are indicated on this page.
  • An asterisk (*) in the relationship attribute column indicates that no relationship attribute (RELA) was assigned.
  • Every even row (indicated by orange colored rel/rela pairs) indicates that the current row is an inverse relationship of the row above it.
  • See Section 2.4 of the UMLS Reference Manual for more information on Relationships in the UMLS Metathesaurus.

Relationship Definitions

  • AQ: allowed qualifier
  • CHD: has child (narrower hierarchical term)
  • DEL: deleted concept
  • PAR: has parent (broader hierarchical term)
  • QB: can be qualifier by
  • RB: has a broader relationship
  • RL: has similar or like relationship
  • RN: has narrower relationship
  • RO: has relationship other than synonymous, narrower or broader
  • RQ: related and possibly synonymous
  • SIB: has sibling
  • SY: source-asserted synonymy
