Likelihood Ratio (Medicine): Basic Definition

https://www.statisticshowto.com/likelihood-ratio/

Likelihood ratios range from zero to infinity. The higher the value, the more likely the patient has the condition. As an example, let’s say a positive test result has an LR of 9.2. This result is 9.2 times more likely to happen in a patient with the condition than it would in a patient without the condition. A rule of … See more
