Equations used
 

FactorSum = AgeRange + Sex + ClinicalAndXrayFactors

Risk = 100 / (1 + e(3.26-FactorSum))

 

 

Calculation Details and Variables

• Equation parameters such as Age Range, have two or more discrete values that may be used in the calculation. The numbers in the parentheses, e.g. (0), represent the values that will be used.
