About the calculator: The underlying model was built using data from six US community-based cohorts including the National Health and Nutrition Examination Surveys as well as the US mortality rate from Vital Statistics to estimate the prevalence and 1-year risk of developing PAD, defined as an ankle-brachial index (ABI) <0.90, at each year of age from birth to 80 years for White, Black, and Hispanic men and women. Markov Monte Carlo simulations in a simulated cohort of 100,000 individuals were then used to estimate lifetime risk of PAD. Prevalence and residual lifetime risk of PAD according to combinations of traditional atherosclerotic risk factors above, were developed based on odds ratios of PAD.
