Likelihood ratio
The likelihood ratio is defined as the probability of obtaining a positive test result in a patient with the disease divided by the probability of obtaining a positive test result in a patient without the disease1.
Calculation
Likelihood ratio vs Sensitivity
The likelihood ratio is defined as the probability of obtaining a positive test result in a patient with the disease divided by the probability of obtaining a positive test result in a patient without the disease1.
Sensitivity is the probability of obtaining a positive test result in a patient with the disease1.
