## Bayes' post Reviews in United States

### *---- "Calculations correct?"
Stark but effective interface. Seems to calculate things incorrectly some times, correctly others. Could just be me, but even the screenshot seems wrong: shouldn't 0.65, 0.75, and 0.85 yield 0.62?

### ***** "Clinically useful"
Use it in conjunction with ACC/AHA stable angina guideline all the time.  Thanks.
