About LDL Cholesterol Calculator

1. The Ciccarone Center for the Prevention of Cardiovascular Disease at Johns Hopkins has developed this app to provide automated calculation of LDL cholesterol by the method published by Martin and colleagues in the Journal of the American Medical Association (doi:10. 1001/jama. 2013. 280532).

2. Rather than the traditional one-size-fits-all approach of dividing triglycerides by a fixed factor, the Martin equation matches each person with a personalized factor to calculate the LDL cholesterol level.

3. For-profit companies or anyone intending to redisplay or incorporate the LDL-C calculator must secure a license from the Johns Hopkins University.
