Originally, we stated in 2007 that we will accept the retrospective registration until January 1, 2008; in 2011, we extended the deadline of retrospective registration to January 1, 2013. Due to there are still a lot of researchers applying register their studies retrospectively, we decide: from January 1, 2013, anyone who hope to register their studies retrospectively, have to provide the raw data of the study to be the evidence of the study was existed, and the raw data should be public accessible. The raw data has to be provided via ResMan, the public management platform of clinical trials database. The use of ResMan is voluntary, public welfare no charge on software. Only 3,000 yuan RMB (500 USD) should be paid for the database occupation and service of reviewing the raw data.
