Clinical Trials often Unregistered, Unpublished

September 13, 2017

(Eurekalert) – An analysis of more than 100 clinical trials found that they were often unregistered, unpublished and had discrepancies in the reporting of primary outcomes, according to a study published by JAMA. The study is being released to coincide with its presentation at the Eighth International Congress on Peer Review and Scientific Publication. A major aim of trial registration is to help identify and deter the selective reporting of outcomes based on the results.
