The Clinical Measurement Ontology (CMO), Measurement Methods Ontology (MMO), and Experimental Condition Ontology (XCO) are currently being developed at the Rat Genome Database. For more information about these vocabularies please see Shimoyama et al. Three ontologies to define phenotype measurement data. Front Genet. 2012;3:87.

Any measurement in which the number of individuals in a study population that display relapsing-remitting experimental autoimmune encephalomyelitis (R-EAE) at a point in time or develop R-EAE within a determined period of time are compared to the total number of individuals in the study population. Often expressed as a percentage but could be expressed as a ratio. Relapsing-remitting EAE is an animal model of brain inflammation in which inflammation is induced through immunization of the animal with central nervous system antigens or by the passive transfer of autoreactive T cells where such induction results in a disease characterized by repeated symptomatic attacks followed by complete or almost complete improvement.
