Evidence class

Evidence The Evidence Resource provides a machine-interpretable expression of an evidence concept including the evidence variables (e.g., population, exposures/interventions, comparators, outcomes, measured variables, confounding variables), the statistics, and the certainty of this evidence.

Copy function for Evidence Returns a copy of the current instance with the provided fields modified. If a field is not provided, it will retain its original value. If a null is provided, this will clearn the field, unless the field is required, in which case it will keep its current value.

final, inherited

extension_ → List<FhirExtension>?

May be used to represent additional information that is not part of the basic definition of the resource. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.",

identifier A formal identifier that is used to identify this summary when it is represented in other formats, or referenced in a specification, model, design or an instance.

final

implicitRules → FhirUri?

A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.

final, inherited

modifierExtension → List<FhirExtension>?

May be used to represent additional information that is not part of the basic definition of the resource and that modifies the understanding of the element that contains it and/or the understanding of the containing element\u0027s descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions.\n\nModifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).",
