Left Ventricular Thrombus: Likelihood Ratios

Introduction: None written.

The likelihood ratios of findings for Left Ventricular Thrombus 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.)

in a population with high prevalence of LV thrombus. Note that accuracy numbers are skewed because 7% of patients were excluded because of poor study quality. Study: Chest. 1983 Feb;83(2):228-32. PMID: 6822107
