Note that this recommendation applies only to clinical trials on which the article is reporting. Any other clinical trial references that are present should remain as URL links in the text and should not be converted to references/citations or to a &lt;related-object&gt;.</p> <p>For the purpose of registration, a clinical trial is any research study that prospectively assigns human participants or groups of humans to one or more health-related interventions to evaluate the effects on health outcomes. Interventions include, but are not restricted to, drugs, cells, and other biological products, surgical procedures, radiological procedures, devices, behavioural treatments, process-of-care change, and preventive care. (<a href="http://www.who.int/topics/clinical_trials/en/">http://www.who.int/topics/clinical_trials/en/</a>)</p> <p>Clinical trials are identified by a clinical trial number, which is unique within any given registry but not necessarily unique across registries. Thus, both the registry and the clinical trial number must be provided to accurately identify the clinical trial.</p> <p>Although editorial decision-making is normally outside JATS4R&#8217;s purview, it is recommended that all clinical trials should: <br></p> <ol class="wp-block-list"> <li>be registered in WHO-approved databases,</li> <li>be listed on the WHO&nbsp;<a href="https://www.who.int/ictrp/network/en/">International Clinical Trials Registry Platform</a>&nbsp;(ICTRP), and</li> <li>associate a Crossref DOI in the metadata. Crossref provides an&nbsp;<a href="http://api.crossref.org/works/10.18810/registries/transform/application/vnd.crossref.unixsd+xml">API</a>&nbsp;that contains both pieces of information (DOI and Name) and the JATS4R Validator tool will use this to provide warning messages if registries other than the ones listed by Crossref are used.</li> </ol> <p>Note: The International Committee of Medical Journal Editors (ICMJE) has indicated that clinical trials should be listed at the end of the abstract, a recommendation which was based on requirements of visual appearance, rather than on those of machine-readability or XML. Additionally, the ICMJE&#8217;s recommendation was made at an earlier time, before there was a need to include so many pieces of additional metadata important to an article. Thus, the ICMJE&#8217;s recommendation has not been included as part of this recommendation.</p> <h2 class="wp-block-heading" id="additional-reading" >Additional reading</h2> <ul class="wp-block-list"> <li><a href="http://www.who.int/ictrp/en/" target="_blank" rel="noreferrer noopener">http://www.who.int/ictrp/en/</a></li> <li><a href="https://support.crossref.org/hc/en-us/articles/115000110103-Linked-Clinical-Trials" target="_blank" rel="noreferrer noopener">https://support.crossref.org/hc/en-us/articles/115000110103-Linked-Clinical-Trials</a></li> <li><a href="http://www.icmje.org/recommendations/browse/publishing-and-editorial-issues/clinical-trial-registration.html" target="_blank" rel="noreferrer noopener">http://www.icmje.org/recommendations/browse/publishing-and-editorial-issues/clinical-trial-registration.html</a></li> <li><a href="https://trialsjournal.biomedcentral.com/articles/10.1186/s13063-016-1686-5" target="_blank" rel="noreferrer noopener">https://trialsjournal.biomedcentral.com/articles/10.1186/s13063-016-1686-5</a></li> </ul> <h2 class="wp-block-heading" id="recommendation" >Recommendation</h2> <ol class="wp-block-list"> <li><strong>&lt;related-object></strong>. Contain each clinical trial within a separate &lt;related-object> element (i.e. one per clinical trial).
