Current Eligibility refers to the current FDA-approved eligibility criteria for PCSK9 inhibitors. Extended Eligibility refers to using PCSK9 inhibitors as primary prevention therapy for those without clinical CVD but who possess CVD high-risk equivalents.

*

The result differences compared with the status quo scenario.

**

The results were calculated from age 51 until death.

Total incidence before age 79 for a 1,000 individuals without the disease at age 51. Disability-free life expectancy refers to reporting no instrumental activity of daily living or activity of daily living limitations and not living in a nursing home. Quality-adjusted life-years adjust length of life for quality based on a person’s chronic conditions and functional status. 95% confidence intervals of the difference estimates are presented in brackets, indicating the uncertainty of the effectiveness of PCSK9 inhibitors. The 95% confidence intervals for the mean values in each scenario can be found in the Supplemental Appendix.
