What it means
Surrogates are useful, but a change in a marker does not always translate into a change people feel or into lower disease risk. Telomere length, for example, is a marker, and a rise in it does not on its own show that a supplement extends life.
Clinical endpoints, such as vision, symptoms or survival, carry more weight.
Also known as
- surrogate outcome
