Guidance

This resource is used to define the eligibility criteria for a specific study.

Categories

The following categories are used to describe the population of the patients in the Eligibility Criteria resources (Recommendation Eligibility Criteria, Study Eligibility Criteria).

The categories are defined as slices of the characteristic element in the respective resource.

Fixed Codes:
