Public Disclosure of Clinical Trial Results

Reporting of Findings of Clinical Trials

When researchers embark on a clinical trial, they make a commitment to conduct the trial and to report the findings in accordance with basic ethical principles. This includes preserving the accuracy of the results and making both positive and negative results publicly available. However, a significant proportion of healthcare research remains unpublished and, even when it is published, some researchers do not make all of their results available. Selective reporting, regardless of the reason for it, leads to an incomplete and potentially biased view of the trial and its results. For more information please refer to "Reporting the Findings of Clinical Trials" in The Bulletin.

WHO Statement on Public Disclosure of Clinical Trials Results

On April 14, 2015, the World Health Organization (WHO) published a new statement on the public disclosure of clinical trial results . The WHO statement defines reporting timeframes, calls for results-reporting of older but still unpublished trials, and outlines steps to improve linkages between clinical trial registry entries and their published results.

A public consultation process has been done previously on the original draft statement on public disclosure of clinical trials results and all the comments submitted were taken into consideration when the new statement was written.
