Abbreviations: FHS – Framingham Heart Study, SBP – systolic blood pressure, DBP – diastolic blood pressure

Each p-value > 0.05 comparing SBP to the FHS model, overall and for each race-ethnicity.

Each p-value <0.001 comparing DBP with age to the FHS model, overall and for each race-ethnicity.

The Framingham model includes age, sex, body mass index, current smoking, family history of hypertension and systolic and diastolic blood pressure modeled using the equation-based system (see methods for additional details). The systolic blood pressure model uses systolic blood pressure modeled in 7 categories (<110, 110 – 114, 115 – 119, 120 – 124, 125 – 129, 130 – 134 and 135 – 139 mmHg). The diastolic blood pressure with age model includes 20 categories (diastolic blood pressure levels of <70, 70 – 74, 75 – 79, 80 – 84, and 85 – 89 mmHg for each age group <50, 50 – 59, 60 – 69, and ≥ 70 years). The SBP model includes the 7 SBP categories. The DBP with age model includes the 20 diastolic blood pressure with age categories.
