Big-data Clinical Trial (BCT): the third talk

In the previous talk, the randomized control trial (RCT) showed less possibility to keep its major role in the future clinical studies (1). Meanwhile, the concept of “Big-data Clinical Trial (BCT)” was discussed and redefined in the following articles (2,3). In this article, we will continue the topic on BCT from the perspective of “data structure”. We hope BCT will have an adequate arena to take over RCT and win the “relay race” in the upcoming new era.
