Consequently, the exact definition of the multivariate risk groups used in the present analyses is not particularly relevant to the extrapolation of the findings. However, these estimates of cost-effectiveness at different levels of risk are likely to be generalisable to a wide range of different settings using appropriate local data to estimate the risks for particular individuals. Current guidelines 20,21 generally recommend the initiation of statin therapy when the estimated 10-year risk of a non-fatal heart attack or coronary death is at least 1520%.
