  "description": "A form for calculating the 10-year-risk of Hard Coronary Heart Disease.  The constants used in the formula match those in https://www.framinghamheartstudy.org/fhs-risk-functions/hard-coronary-heart-disease-10-year-risk/, but the actual formulas are not listed there, and so we have not been able to verify them.  However, the output of this form matches the output of a perl program (from which the formulas were taken) which matched the output of a calculator on a website, which regrettably no longer exists.  So, while this form is good enough or a demo, it should not be relied on for real purposes without first verifying its formulas or its output against some other source.",
