This code system defines the following codes:

active ActiveStudy is opened for accrual.
active-but-not-recruiting Active, not recruitingThe study is ongoing, and participants are receiving an intervention or being examined, but potential participants are not currently being recruited or enrolled.
administratively-completed Administratively CompletedStudy is completed prematurely and will not resume; patients are no longer examined nor treated.
approved ApprovedProtocol is approved by the review board.
closed-to-accrual Closed to AccrualStudy is closed for accrual; patients can be examined and treated.
closed-to-accrual-and-intervention Closed to Accrual and InterventionStudy is closed to accrual and intervention, i.e. the study is closed to enrollment, all study subjects have completed treatment or intervention but are still being followed according to the primary objective of the study.
completed CompletedThe study closed according to the study plan. There will be no further treatments, interventions or data collection.
disapproved DisapprovedProtocol was disapproved by the review board.
enrolling-by-invitation Enrolling by invitationThe study is selecting its participants from a population, or group of people, decided on by the researchers in advance.

not-yet-recruiting Not yet recruitingThe study has not started recruiting participants.

CodeThe code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
DisplayThe display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
