Study types

It is useful to provide a very broad overall classification of clinical studies as to their type. The classification in the MDR system is taken from ClinicalTrials.gov, and is listed below:

11	Interventional	A clinical trial.	ClinicalTrials.gov
12	Observational	Any form of non-interventional research.	ClinicalTrials.gov
13	Observational Patient Registry	Collecting data for a designated registry.	ClinicalTrials.gov
14	Expanded access	Off label usage of a new product for individuals.	ClinicalTrials.gov
15	Funded programme	With a single or linked series of grants.	ClinicalTrials.gov
0	Not yet known	Dummy value supplied by default on entity creation.	ClinicalTrials.gov
