Specialised register

The Cochrane EPOC specialised trials register is no longer maintained following an exemption granted by Cochrane's Editor-in-Chief on the advice of the Cochrane Information Specialists' Executive:

The exemption was given due to the diverse scope of the EPOC group, and its inclusion of studies other than randomised trials. In addition it was accepted that it isn’t possible to define ‘a priori’ all the topics that the group may cover.

Attempts were made to maintain a specialised trials register which ceased updates in around 2014. The entirety of the register as it existed is searchable via CENTRAL (Cochrane Central Register of Controlled Trials) in the Cochrane Library.
