Introduction

Aim:

Students will gain foundational knowledge in understanding and calculating likelihood ratios. Students will also learn how to apply this knowledge to clinical situations and will be introduced to the Rational Clinical Examination series published by the Journal of the American Medical Association.

Learning Objectives

By the end of this module, you should be able to:
  1. Define the Likelihood Ratio (LR).
  2. Calculate both the positive and negative LR for a diagnostic test.
  3. Interpret what the LR represents in a clinical scenario.
  4. Use a Fagan Nomogram to determine a patients probability of having disease based on their test result.
