CLINICAL MEASUREMENT - ANNOTATIONS

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.

Definition:The calculated difference in urine vanillylmandelic acid excretion rate between two points in time or two conditions expressed as the result of the subtraction in and of itself without comparison by ratio with another quantity.
Comment:The term "absolute change" refers to the subtraction of one value from another, as opposed to a dissimilarity of two values expressed as a ratio or as a percentage. In this context it is not intended to necessarily imply the difference expressed as an absolute value |n|, that is, the numeric value of the difference without regard to its sign.
Synonyms:exact_synonym: absolute change in urine 3-methoxy-4-hydroxymandelic acid excretion rate
