Logical Definition (CLD)



Expansion based on codesystem StatisticSynthesisType v2.0.0 (CodeSystem)

This value set contains 8 concepts.

  std-MAhttp://terminology.hl7.org/CodeSystem/synthesis-typesummary data meta-analysis

A meta-analysis of the summary data of estimates from individual studies or data sets.

  IPD-MAhttp://terminology.hl7.org/CodeSystem/synthesis-typeindividual patient data meta-analysis

A meta-analysis of the individual participant data from individual studies or data sets.

  indirect-NMAhttp://terminology.hl7.org/CodeSystem/synthesis-typeindirect network meta-analysis

An indirect meta-analysis derived from 2 or more direct comparisons in a network meta-analysis.

  combined-NMAhttp://terminology.hl7.org/CodeSystem/synthesis-typecombined direct plus indirect network meta-analysis

An composite meta-analysis derived from direct comparisons and indirect comparisons in a network meta-analysis.

  rangehttp://terminology.hl7.org/CodeSystem/synthesis-typerange of results

A range of results across a body of evidence.

  classificationhttp://terminology.hl7.org/CodeSystem/synthesis-typeclassifcation of results

An approach describing a body of evidence by categorically classifying individual studies (eg 3 studies showed beneft and 2 studied found no effect).

  NotApplicablehttp://terminology.hl7.org/CodeSystem/synthesis-typenot applicable

Not applicable because the evidence is not from a synthesis but from a single study. Used fo explicitly state that it's not a synthesis.

  pooledhttp://terminology.hl7.org/CodeSystem/synthesis-typepooled ratesinactive

An unweighted average.

Explanation of the columns that may appear on this page:

Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies
System 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)
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
