[Clinical trial registration system and evidence-based medicine].

The authors briefly introduced the management of clinical test for new drug development, clinical trials for drugs prepared in hospital and post-market drugs, and other types of clinical trials. The mechanism of WHO International Clinical Trial Register Platform (WHO ICTRP), Chinese Clinical Trial Register (ChiCTR) and Chinese Clinical Trial Registration and Publishing Collaboration (ChiCTRPC) were also introduced. The authors suggested the trialists to practice the basic philosophy of evidence-based medicine as the rules of their thought and action, and considered that this is the inner guarantee system for the validity of clinical trials.
