This oid is used as an identifier II.root to indicate the the extension is an absolute URI (technically, an IRI). Typically, this is used for OIDs and GUIDs. Note that when this OID is used with OIDs and GUIDs, the II.extension should start with urn:oid or urn:uuid: 

Note that this OID is created to aid with interconversion between CDA and FHIR - FHIR uses urn:ietf:rfc:3986 as equivalent to this OID. URIs as identifiers appear more commonly in FHIR.

This OID may also be used in CD.codeSystem.">Uniform Resource Identifier (URI)</a>/urn:oid:2.16.840.1.113883.4.642.40.44.22.191</p><p><b>version</b>: 1.0.0-ballot3</p><p><b>name</b>: NCT03640312_otherOutcomeMeasure_5_OG001</p><p><b>title</b>: Mean Change in Blood Urea Nitrogen at 12 weeks for Candesartan in NCT03640312</p><p><b>citeAs</b>: </p><div><p>Mean Change in Blood Urea Nitrogen at 12 weeks for Candesartan in NCT03640312 [Database Entry: FHIR Evidence Resource].
