The article discusses the use of likelihood ratio (LR) in making diagnosis of a disease. LR summarizes information about the diagnostic test by combining information about the sensitivity and specificity. It tells how much a positive or negative result changes the likelihood that a patient would have the disease. It is very useful in interpreting diagnosis of several diseases including coronary artery disease.
