Web8 Jun 2024 · The likelihood ratio of a negative test is .05. If a line is drawn from the pretest probability of 10% through the likelihood ratio of .05, we are left with a posttest probability of 0.5%. This means that after a negative test, a person's probability of having the disease of interest drops from 10% to 0.5%.
