Union of http://hl7.org/fhir/uv/ebm/StructureDefinition/comparator-group and http://hl7.org/fhir/uv/ebm/StructureDefinition/comparator-group

This is the set of resources that conform to either of the profiles ComparatorGroup (http://hl7.org/fhir/uv/ebm/StructureDefinition/comparator-group) and ComparatorGroup (http://hl7.org/fhir/uv/ebm/StructureDefinition/comparator-group). E.g. what you have to deal with if you get resources conforming to one of them
