III. Interpretation
- Factors (sum these)
- E * 1.713
- A * 0.847
- R * 0.607
- V * 1.417
- S * 2.085
- H * 1.208
- T * 0.089
- Calculation
- Probability = 1/1+e^-FactorSum
- Result is the predicted probability for short-term adverse cardiac outcome (<1% is considered low risk)
IV. Efficacy
- Test Sensitivity 98-99%
