Generated Narrative: CodeSystem group-characteristic-combination

This case-sensitive code system http://hl7.org/fhir/group-characteristic-combination defines the following codes:

Code	Display	Definition
all-of	All of	Combine characteristics with AND.
any-of	Any of	Combine characteristics with OR.
at-least	At least	Meet at least the threshold number of characteristics for definition.
at-most	At most	Meet at most the threshold number of characteristics for definition.
except-subset	Except subset	Meet the inclusion criteria under the condition that the basis does not match the exclusion criteria.
statistical	Statistical	Combine characteristics statistically. Use method to specify the statistical method.
net-effect	Net effect	Combine characteristics by addition of benefits and subtraction of harms.
dataset	Dataset	Combine characteristics as a collection used as the dataset.
