This example of a GroupAssignment Profile describes a 2-group study (so handling='dichotomous') and lists the 2 study arms in category.name elements. Because the definition of this EvidenceVariable Resource is fully expressed in the handling and category elements, the definition.concept element uses a CodeableConcept for 'Defined in handling and category elements'.
