Resource Profile: NetEffectContribution

Profile of Evidence for Evidence Based Medicine IG. The NetEffectContribution Profile is used for evidence in which the effect estimates, expressed as risk differences, is multiplied by a relative importance rating of the outcomes.

Usage:

• Refer to this Resource Profile: NetEffectContributionList and SummaryOfNetEffect
• Examples for this Resource Profile: NetEffectContribution_All_cause_mortality_for_Example_for_GIN_2022, NetEffectContribution_Nonfatal_myocardial_infarction_or_stroke_for_Example_for_GIN_2022, NetEffectContribution_Remission_of_diabetes_for_Example_for_GIN_2022, NetEffectContribution_New_onset_depression_for_Example_for_GIN_2022...

Constraints

Id	Grade	Path(s)	Details	Requirements
cnl-0	warning	Evidence	Name should be usable as an identifier for the module by machine processing applications such as code generation : name.exists() implies name.matches('^[A-Z]([A-Za-z0-9_]){1,254}$')
cnl-1	warning	Evidence.url	URL should not contain | or # - these characters make processing canonical references problematic : exists() implies matches('^[^|# ]+$')
ele-1	error	**ALL** elements	All FHIR elements must have a @value or children : hasValue() or (children().count() > id.count())

This structure is derived from ComparativeEvidence

Summary

Mandatory: 10 elements(2 nested mandatory elements)
Must-Support: 4 elements
Prohibited: 1 element

Structures

This structure refers to these other structures:

• OutcomeImportance (http://hl7.org/fhir/uv/ebm/StructureDefinition/outcome-importance)

Slices

This structure defines the following Slices:

• The element 1 is sliced based on the value of Evidence.relatedArtifact
• The element 1 is sliced based on the value of Evidence.statistic
• The element 1 is sliced based on the value of Evidence.statistic.attributeEstimate
• The element 1 is sliced based on the value of Evidence.statistic.modelCharacteristic
