Clinical Trials, Links to

“Tagging” Clinical Trial Descriptions in JATS means tagging external links to clinical trial descriptions that identify the Clinical Trial registry and have a Crossref or other identifier for the trial. Clinical trial registration information from https://clinicaltrials.gov/ is typically displayed as a simple link plus the registration number, e.g.:
Trial registration: NCT02442440 (https://register.clinicaltrials.gov/)
In JATS tagging, there are two convenient ways to encode this information: as a simple <ext-link> or as a more complex link using an <related-object> element.
