EBM Calculator
The goal of EBM Calculator is to help with your appraisal of the medical literature!
Effect Calculator
- Used for studies that examine the effect of a therapy or exposure.
- Calculate key effect estimates for dichotomous outcomes, including:
- Absolute Risk Reduction (ARR)
- Number Needed to Treat (NNT)
- Risk Ratio (RR)
- Relative Risk Reduction (RRR)
- Odds Ratio (OR)
- Each measure is accompanied by a 95% Confidence Interval to assess the precision of the effect.
Diagnostic Test Calculator
- Evaluate the utility of diagnostic tests using metrics like:
- Sensitivity
- Specificity
- Likelihood Ratios (LR+ and LR-)
- Positive Predictive Value (PPV)
- Negative Predictive Value (NPV)
- Each measure includes a 95% Confidence Interval to ensure accurate evaluation.
Post-Test Probability Calculator
- Estimate the likelihood of a condition or disease based on the result of a diagnostic test.
- Calculate Post-Test Probability using Sensitivity, Specificity, or Likelihood Ratios.
- Use an Interactive Fagan Nomogram to see how Post-Test Probability changes.
