A: No. Dates are not obfuscated in TriNetX.

Q: Is patient count obfuscated when running a query in TriNetX?

A: Yes, patient count is obfuscated in two ways:

  1. Patient count is rounded up to the nearest 10 for all cohort sizes.
  2. When a query returns a single count (<10), a count of 10 will be reported, and you won’t be able to explore this cohort. You will get this message: “The cohort size is too small so detailed information cannot be displayed.”

Q: Can patients be identified in TriNetX?

A: No. Only patient counts are returned.

Q: Can patient-level data be obtained using TriNetX?

A: Yes. To get identifiable data, Limited Data Sets, or De-Identified data for your patient cohort for IRB approved studies or other qualified studies, please contact CTSI Informatics team.
