Exostosis: Likelihood Ratios

Introduction: Slow-growing bony lesions of the external auditory canal, usually multiple, often associated with swimming in cold water

The likelihood ratios of findings for Exostosis are listed below. See the left navigation bar to change the display.

Pre-Test Probability (Prevalence): %.	Post-Test Probability (Predictive Value): %.	Switch to display mode.
Note that calculating probabilities from more than one** finding is inherently inaccurate because findings are not independent. (For example, using two positive findings that share a common pathogenesis is likely to overestimate the true probability.)
