Researchers are very satisfied with Castor EDC; based on their study protocol they can easily build their study structure, and change it when necessary. It is very nice to see how creative they can become: one particular researcher was so creative that he incorporated a large part of the protocol in the study structure.Researchers can do fantastic things with Castor EDC!
