That is a model without the effect. Post-test probability for negative test c cd 30 120 25 025. You can select any level of significance you require for the confidence intervals.

The likelihood ratio can be used to calculate the post-test odds from the pre-test odds of disease. Using these equations you can calculate the post-test probability of disease from the. Below is a table showing how to calculate likelihood ratios with 3 or more risk groups or outcomes.

Pretest Probability Likelihood Ratio Posttest Probability J. Also calculates likelihood ratios PLR NLR and post-test probability. The positive likelihood ratio LR tells us how much to increase the probability of disease if the test is positive while the negative likelihood ratio LR- tells us how much to decrease it.
