Those of us who attended the 2017 spring conference in Birmingham were treated to an excellent symposium on transparency in clinical trials, where EU Policy 00701 on disclosure of clinical data was a key focus. A month later, theICMJE (International Committee of Medical Journal Editors) announced that beginning in July 2018 they will require that submitted manuscripts based on clinical trials carry a data sharing statement.2Data sharing statements will be expected to describe the following: whether data will be shared; what will be shared; and when and for how long the data will be available.3 Also, from 2019 new trials will have to include a data sharing plan in their registration information.
