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.
