The likelihood ratios of findings for Nephrolithiasis 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.)
