Observed relative risks for smoking and physical activity simulated under the null hypothesis for men age < 60 and for men age 60+. The observed relative risks were simulated using four preclinical duration distribution parameters for the mode (1, 5, 10, 20) and three standard deviation (sd) (1,4,8). For the smoking variable, the risk is for “ever smoked” compared to “never smoked.” For total physical activity ages 50 and up, the risk is for 3 or more hours per week compared to less than 3 hours per week; men less than 50 years were not included.
