Distribution of 10-year ASCVD risk in the low-prevalence subgroups

10-year ASCVD Risk*	Men < 40 years (non-smokers, non-hypertensive) N=1,365	Women <50 years (non-smokers, non-hypertensive) N=3,281
<0.1%	2.2% (1.5%–3.4%)	7.7% (6.8%–8.8%)
0.1% – 0.49%	44.9% (41.9%–48.0%)	58.7% (56.3%–61.1%)
0.5% – 0.99%	27.3% (24.8%–29.9%)	23.3% (21.3%–25.4%)
1.0% – 2.4%	23.3% (20.6%–25.9%)	10.0% (8.6%–11.6%)
2.5% – 4.9%	2.2% (1.6%–3.2%)	0.2% (0.1%–0.5%)
5.0% – 7.4%	0.09% (0.02%–0.4%)	0.04% (0.0%–0.3%)

Brackets show 95% confidence intervals for that subgroup.

^*Risk calculated using 2013 ACC/AHA Sex and Race specific Pooled Cohort Equations. Low-prevalence subgroups defined as those subgroups in which we could rule out a prevalence of elevated cardiovascular risk (10-year ASCVD risk >5%) of more than 1%; and included non-smoking, non-hypertensive men under age of 40 years and non-smoking, non-hypertensive women under age of 50 years.
