The computer model predicts that about 1 in 9 adults will die within 10 years, and about 1 in 40 from heart disease, which matches real death rates from national health surveys.
Claim Context
In a U.S. population of adults aged 35–80 years, the CVD PREDICT micro-simulation model projects a 10-year all-cause mortality risk of 10.9% and a CVD-specific mortality risk of 2.6%, with these estimates falling within the 95% confidence intervals of observed NHANES data (11.2% and 2.2%, respectively), supporting the model's calibration for population-level mortality forecasting.
“Observed 10-year all-cause mortality in NHANES versus the simulation model were 11.2% (95% CI: 10.3–12.2%) versus 10.9%; corresponding results for CVD mortality were 2.2% (1.8–2.7%) versus 2.6%.”

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether multiple models converge on similar mortality estimates for the same population.
A systematic review of all published CVD micro-simulation models that reports their projected 10-year all-cause and CVD mortality rates for a U.S. population aged 35–80, assessing heterogeneity and agreement with NHANES or other national data.
The true 10-year mortality risk in a representative population.
A prospective cohort study of 10,000 U.S. adults aged 35–80 recruited in 1999–2000 and followed through 2011 with complete mortality ascertainment and cause-of-death coding, estimating 10-year all-cause and CVD mortality with 95% confidence intervals.
Whether interventions that reduce modeled risk actually reduce real mortality.
A large RCT of statin therapy in 20,000 U.S. adults aged 35–80 with moderate CVD risk, comparing 10-year mortality and CVD events in statin vs placebo groups, to test whether the magnitude of benefit matches model predictions.
