Comments Posting comment... By: remler (8 month(s) ago) very good job Dr. Nelson. The audio did not work on my computer but since I was there the text you did was a great help. my main question is for the meat and potatoes doctor what do I gain by thinking in likelihood ratio rather than positive and negative predictive value.

Both canals recently flushed clear. Still c/o right-sided hearing loss. Canals clear on exam with normal TMs. What Next? : What Next? What Next? : What Next? Weber’s Rinne’s Case : Case Rinne’s shows BC > AC on the right, Weber’s is midline. How do you interpret this? Likelihood Ratios : Likelihood Ratios Likelihood ratios greater than 1 indicate that the finding makes the disease more likely. Likelihood ratios less than 1 indicate that the finding makes the disease less likely. LR = Likelihood of the finding in disease Likelihood of the same finding in health Using Likelihood Ratios : Using Likelihood Ratios Likelihood ratios are odds Odds are not the same as probability To get from one to the other and back, you can use this handy nomogram LRs for Weber and Rinne : LRs for Weber and Rinne Application : Application Rinne BC > AC for conductive hearing loss Application : Application Rinne BC > AC for conductive hearing loss Rinne AC > BC against conductive hearing loss Application : Application Rinne BC > AC for conductive hearing loss Weber for NS hearing loss Rinne AC > BC against conductive hearing loss Application : Application Rinne BC > AC for conductive hearing loss Weber for NS hearing loss Weber against conductive hearing loss Rinne AC > BC against conductive hearing loss Application : Application Weber’s either for conductive hearing loss or against NS hearing loss You do not have the permission to view this presentation.
