    • MAK GRACE Module 1 on Sampling Frame in Diagnostic Test Accuracy Studies Media Resource

      GRACE (Guidelines for Reasonable and Appropriate Care in the Emergency Department) is a project of the Society for Academic Emergency Medicine.  They asked me (Michael) to record a series of videos on how to evaluate studies of diagnostic test acccuracy (DTA studies).  I have recorded two modules so far and am posting them here.
