MedicalGuideline

Any recommendation made by a standard society (e.g. ACC/AHA) or consensus statement that denotes how to diagnose and treat a particular condition. Note: this type should be used to tag the actual guideline recommendation; if the guideline recommendation occurs in a larger scholarly article, use MedicalScholarlyArticle to tag the overall article, not this type. Note also: the organization making the recommendation should be captured in the recognizingAuthority base property of MedicalEntity.

Property	Expected Type	Description
Properties from Thing
`additionalType`	URL	An additional type for the item, typically used for adding more specific types from external vocabularies in microdata syntax. This is a relationship between something and a class that the thing is in. In RDFa syntax, it is better to use the native RDFa syntax - the 'typeof' attribute - for multiple types. Schema.org tools may have only weaker understanding of extra types, in particular those defined externally.
`description`	Text	A short description of the item.
`image`	URL	URL of an image of the item.
`name`	Text	The name of the item.
`url`	URL	URL of the item.
Properties from MedicalEntity
`alternateName`	Text	Any alternate name for this medical entity.
`code`	MedicalCode	A medical code for the entity, taken from a controlled vocabulary or ontology such as ICD-9, DiseasesDB, MeSH, SNOMED-CT, RxNorm, etc.
`guideline`	MedicalGuideline	A medical guideline related to this entity.
`medicineSystem`	MedicineSystem	The system of medicine that includes this MedicalEntity, for example 'evidence-based', 'homeopathic', 'chiropractic', etc.
`recognizingAuthority`	Organization	If applicable, the organization that officially recognizes this entity as part of its endorsed system of medicine.
`relevantSpecialty`	MedicalSpecialty	If applicable, a medical specialty in which this entity is relevant.
`study`	MedicalStudy	A medical study or trial related to this entity.
Properties from MedicalGuideline
`evidenceLevel`	MedicalEvidenceLevel	Strength of evidence of the data used to formulate the guideline (enumerated).
`evidenceOrigin`	Text	Source of the data used to formulate the guidance, e.g. RCT, consensus opinion, etc.
`guidelineDate`	Date	Date on which this guideline's recommendation was made.
