Define LR
LR = probability of finding in patient with disease/probability of finding in patient without disease
LRs are a stable measure of a diagnostic test that is based on both the sensitivity AND specificity of the test. They provide an alternative way of describing the performance of a diagnostic test. They can be used to calculate the post-test probability of disease after a positive or negative test.
