Background

* Indicates blank relationship attribute (rela); not all relationships are assigned an attribute.
Orange colored rel/rela pairs indicate that the current row is an inverse relationship of the row above it. All relationships in MRREL.RRF are bi-directional.
Metathesaurus relationships are traditionally read from right to left.
Every row in MRREL.RRF has a RUI (relationship unique identifier).
Samples below are taken from MRREL.RRF, although not every field is shown. Associated terms (str) from MRCONSO.RRF are also shown for clarity.
Relationship abbreviations appear in MRREL, i.e., SY.
'RQ/mapped_from' relationship indicates a relationship between a MEDLINEPLUS Preferred Term and a MeSH Main Heading.
