Evidence Based Medicine on FHIR Implementation Guide
1.0.0-ballot2 - STU 1 ballot International flag

Evidence Based Medicine on FHIR Implementation Guide, published by HL7 International / Clinical Decision Support. This guide is not an authorized publication; it is the continuous build for version 1.0.0-ballot2 built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/HL7/ebm/ and changes regularly. See the Directory of published versions

Resource Profile: DichotomousIntendedOutcome

Profile of EvidenceVariable for Evidence Based Medicine IG. The DichotomousIntendedOutcome Profile is used to provide a common variable definition for the 'intended' variable in the role of 'outcome' in Evidence Resources, to allow mapping evidence with different observed variables that relate to the same intended outcome.
