Expansion based on EvidenceVariableHandling v5.0.0-ballot (CodeSystem)
Code | System | Display | Definition |
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. |

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 |
