How to: Search for clinical trials in the Altmetric Explorer

Patty Smith, 7th December 2021

The Altmetric Explorer enables you to search for a variety of different types of research outputs, including journal articles, books, data sets, and clinical trials. In this post, we’ll discuss how to search for clinical trials. You can use this feature to keep track of the attention your company’s clinical trials are receiving, gain insight on a specific competitor product, or you can search broadly for all trials in a therapeutic area.

As of December 2021, Altmetric tracks attention to trials from using National Clinical Trial IDs or NCT IDs. In an exciting new development, we are currently working on tracking attention to trials in ISRCTN registry via DOI, so stay tuned for that announcement!

To get started searching for clinical trials, click the blue edit search button at the top of the Altmetric Explorer screen to open up your advanced search options. First, let’s discuss how to search broadly for all of the clinical trials Altmetric is tracking. You’ll want to make sure you’re searching the full Altmetric database by checking the ‘full Altmetric database’ box in the upper right corner.

Note: you will not see this checkbox if your company does not have a custom data integration. If that is the case, skip this step.






Next, scroll down a bit and you’ll see that you can limit the ‘type of output’ to clinical trial records. If you run your search now, you’ll be able to view all of the clinical trial records with attention that Altmetric is tracking.





If you want to be more specific about the topic you’re searching, you’ll probably want to take a different approach. Another way to search is by set of identifiers, in this case, NCT IDs. If you have a known set of clinical trials you’d like to search, you can click the ‘add scholarly identifiers’ button in the advanced search and paste in up to 25,000 NCT IDs. Click the green ‘save’ button and run your search. 










If you’d like to search broadly for clinical trials in a therapeutic area, or you’re not sure what NCT IDs to use, you can start your search at 










Once you run your search for a particular condition, drug name, etc., you can download the results to a CSV file where you can then copy the column with the NCT IDs and paste the results into the ‘add scholarly identifiers’ box in the advanced search of the Altmetric Explorer.
