SBP, systolic blood pressure; DBP, diastolic blood pressure; BP, blood pressure; Q, quintile ; BP, blood pressure; DASH, dietary approaches to stop hypertension.
Main model was adjusted for age, race/ethnicity (non-Hispanic Black v. otherwise), population sample (eight samples for the US), education attainment, family history of high BP, physical activity, alcohol consumption, current smoking status, hypertensive medication use, history of CVD or diabetes, total energy intake and Na/K excretion ratios.
Δ, the difference in BP compared with the third quintile (Q3) of egg intake.
DASH score was calculated based on eight food and nutrient components (fruits, vegetables, whole grains, nuts and legumes, low-fat dairy, red and processed meats, sweetened beverages and Na); the score ranges from 8 to 40, with a higher score corresponds to a healthier diet pattern.
50 g is approximately equivalent to one large egg.
