Clinical Trial Registration in Physiotherapy Journals: Recommendations From the International Society of Physiotherapy Journal Editors

Abstract

Clinical trial registration involves placing the protocol for a clinical trial on a free, publicly available, and electronically searchable register. Registration is considered to be prospective if the protocol is registered before the trial commences (ie, before the first participant is enrolled). Prospective registration has several potential advantages. It could help avoid trials being duplicated unnecessarily and it could allow people with health problems to identify trials in which they might participate. Perhaps more importantly, however, it tackles 2 big problems in clinical research: selective reporting and publication bias. Prospective clinical trial registration is of great potential value to the clinicians, consumers, and researchers who rely on clinical trial data, and that is why the International Society of Physiotherapy Journal Editors (ISPJE) is recommending that members enact a policy for prospective trial registration.
