ValueSet

Expansion performed internally based on codesystem Evidence Variable Handling v6.0.0-ballot3 (CodeSystem)

This value set contains 6 concepts

CodeSystemDisplayDefinition
  boolean http://hl7.org/fhir/variable-handling boolean variable

A boolean variable is a variable which is defined to have only 2 possible values: True or False.

  continuous http://hl7.org/fhir/variable-handling continuous variable

A continuous variable is one for which, within the limits the variable ranges, any value is possible (from STATO http://purl.obolibrary.org/obo/STATO_0000251).

  dichotomous http://hl7.org/fhir/variable-handling dichotomous variable

A dichotomous variable is a categorical variable which is defined to have only 2 categories or possible values (from STATO http://purl.obolibrary.org/obo/STATO_0000090).

  ordinal http://hl7.org/fhir/variable-handling ordinal variable

An ordinal variable is a categorical variable where the discrete possible values are ordered or correspond to an implicit ranking (from STATO http://purl.obolibrary.org/obo/STATO_0000228).

  polychotomous http://hl7.org/fhir/variable-handling polychotomous variable

A polychotomous variable is a categorical variable which is defined to have minimally 2 categories or possible values. (from STATO http://purl.obolibrary.org/obo/STATO_0000087). Suggestion to limit code use to situations when neither dichotomous nor ordinal variables apply.

  extension http://hl7.org/fhir/variable-handling extension

The variable handling is defined in an extension.

Explanation of the columns that may appear on this page:

Lvl A few code lists that FHIR defines are hierarchical - each code is assigned a level. For value sets, levels are mostly used to organize codes for user convenience, but may follow code system hierarchy - see Code System for further information
Source The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code The code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
Display The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
Definition An explanation of the meaning of the concept
Comments Additional notes about how to use the code
