Altmetrics Data (From Altmetric) For About 10,000 Records Now Available

From an Blog Post:

We’re proud to announce today that Altmetric has begun displaying a wealth of online attention paid to clinical trial study records from, the world’s largest registry of clinical trials. Operated by the United States National Library of Medicine (NLM) at the National Institutes of Health, holds registrations from about 200,000 trials from more than 170 countries in the world.

Currently, online attention collected from our various sources since 2014 has been matched to over 10,000 study records from; each of these has its own Altmetric details page.


[Our emphasis] Users of the Altmetric Explorer and Altmetric for Institutions can quickly find all tracked study records by entering “” into the journal filter on the left sidebar. Within the Explorer and AFI, all users can browse through the entire collection of clinical trial study records and read through all the mentions.


[Our emphasis] At the moment, it isn’t possible to use the Altmetric Bookmarklet on pages, but we do plan to do this in future. For now, it’s easiest and quickest to access the data using the Explorer/Altmetric for Institutions and our API.
