The sponsor is responsible for the study
The sponsor is usually the organization responsible for starting, managing, or funding the study. This is one of the most useful details to verify in the official source.
The site runs the study locally
A hospital, clinic, university center, or research site may handle screening, consent, visits, assessments, and follow-up. The sponsor and the local study team are not always the same organization.
Funding does not replace informed consent
Whether a study is publicly funded, charity-funded, or industry-funded, you can ask who pays for it, who reviews it, what happens to your data, and what your right to withdraw looks like.
