Elsevier has pledged to support the further development of the AllTrials campaign to drive greater clinical transparency. We envision this as both a strategic advisory role on how publishers can contribute, and a technical and operational one exploring how we can embed clinical trial registration in our peer review processes, in ScienceDirect and Scopus through the use of unique identifiers to track research on specific trials, in new rules for authors, and in collaborating with fellow publishers to develop new industry standards.
