Registration of Clinical Trials
Publication in IJOA will only be considered for clinical trials that have been registered in a public trials registry. This policy applies to interventional clinical studies in which patient recruitment started after December 2014. In this context, an interventional clinical trial refers to any investigation in which a recruit is prospectively assigned to an intervention or treatment. This decision is supported by the International Committee of Medical Journal Editors (ICMJE). A number of clinical trials registries are endorsed by ICMJE. The largest, ClinicalTrials.gov (https://clinicaltrials.gov/), is run by the National Library of Medicine and contains details on over 160 000 studies. In Europe, the EU clinical trials registry (https://www.clinicaltrialsregister.eu/) currently lists over 23 000 projects: many other national registries are available.
Publication in IJOA of case reports or correspondence in which a patient is potentially identifiable will only be considered if written evidence of patient consent to publication is provided at the time of submission. In addition, the journal recommends the pre-registration of observational clinical trials in a registry (such as those described above); and of protocol details for systematic reviews relevant to the journal ‘s remit in a public registry, for example PROSPERO (https://www.crd.york.ac.uk/prospero/), an international prospective register of systematic reviews.
