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.
