Likelihood ratios (LR) are statistical measures used in diagnostic testing to evaluate the performance of a test in distinguishing between two conditions, usually the presence or absence of a disease. They provide a way to quantify how much a test result changes the odds of a condition being present. There are two types of likelihood ratios: 1. **Positive Likelihood Ratio (LR+)**: This represents the likelihood that a positive test result occurs in individuals with the disease compared to those without the disease.
