It is not appropriate for subjects outside this age range or for subjects who have never smoked. Equations used Logodds = (0.0778868 * (Age - 62)) + Race - (0.0812744 * (Education - 4)) - (0.0274194 * (BodyMassIndex - 27)) + COPD + HxCa + FMHCa + Smoker - (1.822606 * ((10 / Cigarettesperday) - 0.4021541613)) + (0.0317321 * (Yearssmoking - 27)) - (0.0308572 * (Yearssincequittingsmoking - 10)) - 4.532506Risk = 100 * (e(Logodds) / (1 + e(Logodds))) Calculation Details and Variables Equation parameters such as Race, 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.
