University Hospitals Coventry and Warwickshire, Research Development & Innovation has signed up to AllTrials to support AllTrials’ call for all clinical trials data to be reported and ensure that all research data is more readily available in the public domain. The registration of all trials and full reporting of results irrespective of the outcome is a critical step in counteracting the bias towards positive results in the literature. This will provide better quality evidence to enable clinicians to make more informed decisions about patient care.
