Servings/wk were standardized to 2000 kcal/d.
The numbers of persons per tertile of eggs is not equal because of the distribution of egg intake in the study population; ≈45% consumed ≤1 egg/wk, 41% consumed 3 eggs/wk, and 14% consumed >3 eggs/wk.
Mean ± SD (all such values).
P for trend <0.05; estimated by using the median intakes of each quartile continuously in linear regression models for continuous variables and in logistic regression models for categorical variables.
