  div: This case-sensitive code system http://terminology.hl7.org/CodeSystem/variable-role defines the following codes: Code Display Definition population population variable represents a population. subpopulation subpopulation variable represents a subpopulation. exposure exposure variable represents an exposure. referenceExposure reference exposure variable represents a reference exposure. measuredVariable measured variable variable represents a measured variable. confounder confounder variable represents a confounder. measuredVariableA measured variable A variable represents a first of two measured variables to be used in a measured variable that is a mathematical operation of two measured variables. measuredVariableB measured variable B variable represents a second of two measured variables to be used in a measured variable that is a mathematical operation of two measured variables. measuredVariableAB measured variable A to B variable represents a result of a mathematical operation of two measured variables.
