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.
