mapped_to
Connect PT atoms to MeSH Descriptor (if present). Note: Because the combination of the Descriptor and Qualifier taken together represent the expressed relationship, the pair of rels are given a relationship group to link them together.
RO
mapping_qualifier_of
has_mapping_qualifier
Connect PT atoms to MeSH Qualifier (if present). Note: Because the combination of the Descriptor and Qualifier taken together represent the expressed relationship, the pair of rels are given a relationship group to link them together.
SY (no rela)
Connect SY atoms to PT atoms

Hierarchy (MRHIER):

  (return to top)
The hierarchy is created by connecting a health topic with its health topic group using <group id> tag values in mplus_topics_YYYY-MM-DD.xml.
