Notes
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 2.7.1.3.9 in UMLS Documentation Section 2, Metathesaurus for more information on Related Concepts, MRREL.RRF.
