摘要
Surrogate outcome measures have been of interest in clinical research for a long time because of their potential ability to save time and cost. The literature, however, has numerous examples of failed surrogate measures. The definition of a surrogate outcome measure, its consideration in clinical stroke research and some of the potential mechanisms for failure of surrogate measures will be discussed.
