World Association of Medical Editors seeks to promote the highest standards in conducting, reporting, and disseminating medical research in the service of improving personal and public health worldwide. To this end, WAME lends its full support to the AllTrials initiative, extending WAME’s policy that all clinical trials should be registered (http://www.wame.org/resources/policies#trialreg). We echo the call to governments, regulators, research and medical associations, universities, ethics committees, as well as medical journals and publishers, to commit to publishing in full all treatments tested in clinical trials.
