Expansion based on codesystem Evidence Certainty Type v6.0.0-cibuild (CodeSystem)

This value set contains 9 concepts.

  Overallhttp://hl7.org/fhir/certainty-typeOverall certainty

Overall certainty of evidence (quality of evidence).

  RiskOfBiashttp://hl7.org/fhir/certainty-typeRisk of bias

methodologic concerns reducing internal validity.


concerns that findings are not similar enough to support certainty.


concerns reducing external validity.


fuzzy or wide variability.

  PublicationBiashttp://hl7.org/fhir/certainty-typePublication bias

likelihood that what is published misrepresents what is available to publish.

  DoseResponseGradienthttp://hl7.org/fhir/certainty-typeDose response gradient

higher certainty due to dose response relationship.

  PlausibleConfoundinghttp://hl7.org/fhir/certainty-typePlausible confounding

higher certainty due to risk of bias in opposite direction.

  LargeEffecthttp://hl7.org/fhir/certainty-typeLarge effect

higher certainty due to large effect size.

Explanation of the columns that may appear on this page:

LvlA 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
SourceThe source of the definition of the code (when the value set draws in codes defined elsewhere)
CodeThe code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
DisplayThe 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
