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%. Web19 Jan 2024 · Contacts are grouped based on the following logic: Each tier contains 25% of your contacts based on the Likelihood to close score (i.e. contacts with scores in the top 25% are set to Very High, contacts with scores in the bottom 25% are set to Low, etc.). Because the categories are relative groupings, the range of scores in each tier may shift ... fractured foot cast or boot
