methodologic concerns reducing internal validity.


concerns that findings are not similar enough to support certainty.


concerns reducing external validity.


fuzzy or wide variability.

  PublicationBiashttp://terminology.hl7.org/CodeSystem/certainty-subcomponent-typePublication bias

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

  DoseResponseGradienthttp://terminology.hl7.org/CodeSystem/certainty-subcomponent-typeDose response gradient

higher certainty due to dose response relationship.

  PlausibleConfoundinghttp://terminology.hl7.org/CodeSystem/certainty-subcomponent-typePlausible confounding

higher certainty due to risk of bias in opposite direction.

  LargeEffecthttp://terminology.hl7.org/CodeSystem/certainty-subcomponent-typeLarge effect

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
