Researchers can do fantastic things with Castor EDC! Based on their study protocol they can easily build and change their study structure. One particular researcher was so creative that he incorporated a large part of the protocol in the study structure.

What I like about Castor is that I can create a user-friendly database that will also create a user-friendly output, i.e. that I can already prepare the data as much as possible to make data analysis easier.
