[select name="pain" value="One Feature=10|Two Features=20|Three Features=30"] <-- Pain has how many of the following features:
- A - Substernal location
- B - Provoked by exertion or stress
- C - Relieved by rest or nitroglycerin

Pretest probability --> [calc memo="pretest probability" value="score=((gender)*(pain))+(age);score>3003?'94%':score>3002?'93%':score>3001?'87%':score>3000?'76%':score>2003?'72%':score>2002?'65%':score>2001?'51%':score>2000?'34%':score>1003?'27%':score>1002?'20%':score>1001?'13%':score>1000?'4%':score>303?'86%':score>302?'73%':score>301?'55%':score>300?'26%':score>203?'51%':score>202?'31%':score>201?'22%':score>200?'12%':score>103?'14%':score>102?'7%':score>101?'3%':'2%'"]
Interpretation and recommendations:
One approach to pretest probability is to consider <20% low, 20-80% intermediate, and >80% high.
Based on your interpretation of pretest probability levels above, consider:
For high pretest probability: exercise stress test may be performed to aid with prognosis and management.
For intermediate pretest probability: exercise stress test may be performed to aid with diagnosis.
For low pretest probability: exercise stress test may have a role in some circumstances, but is not generally recommended.
