Websites loading from clinicaltrials.gov

Questions

Which websites load from clinicaltrials.gov?

The 196 sites listed on this page. A site is listed when its stored HTML has a script, iframe or stylesheet from the host, or one of its own scripts names the host in an absolute URL.

Is clinicaltrials.gov a third party for every site listed?

Yes: a host under a site's own registrable domain is never recorded for that site, so every site here loads from clinicaltrials.gov as a dependency outside its own domain.
