Evaluating and interpreting the evidence for diagnostic tests
This module will teach students how to critically appraise and apply the best evidence on diagnostic tests. They will learn how to evaluate and interpret the diagnostic accuracy of tests and procedures in different settings. They will also learn how the evidence can inform screening and monitoring programmes.
The last date for receipt of complete applications is 5pm Friday, 5th May 2023. Regrettably, late applications cannot be accepted.
The overall aims of this module are to enable students to:
