0related-toRelated ToThe concepts are related to each other, but the exact relationship is not known.
1  equivalentEquivalentThe definitions of the concepts mean the same thing.
1  source-is-narrower-than-targetSource Is Narrower Than TargetThe source concept is narrower in meaning than the target concept.

Explanation of the columns that may appear on this page:

LvlA few code lists that FHIR defines are hierarchical - each code is assigned a level. For value sets, levels are mostly used to organize codes for user convenience, but may follow code system hierarchy - see Code System for further information
SourceThe source of the definition of the code (when the value set draws in codes defined elsewhere)
CodeThe code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
DisplayThe display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
DefinitionAn explanation of the meaning of the concept
CommentsAdditional notes about how to use the code
