REL (Relationship) REL Description
AQ Allowed qualifier
CHD has child relationship in a Metathesaurus source vocabulary
DEL Deleted concept
PAR has parent relationship in a Metathesaurus source vocabulary
QB can be qualified by.
RB has a broader relationship
RL the relationship is similar or "alike". the two concepts are similar or "alike". In the current edition of the Metathesaurus, most relationships with this attribute are mappings provided by a source, named in SAB and SL; hence concepts linked by this relationship may be synonymous, i.e. self-referential: CUI1 = CUI2. In previous releases, some MeSH Supplementary Concept relationships were represented in this way.
RN has a narrower relationship
RO has relationship other than synonymous, narrower, or broader
RQ related and possibly synonymous.
RU Related, unspecified
SIB has sibling relationship in a Metathesaurus source vocabulary.
SY source asserted synonymy.
XR Not related, no mapping
Empty relationship
