Cardiac function variables, including endocardial fractional shortening (A), midwall fractional shortening (B), and ejection fraction (C), across tertiles of daily phylloquinone intake in 766 adolescents aged 14–18 y. Median (range) intakes of phylloquinone were as follows: tertile 1 = 32 μg/d (8–42 μg/d), n = 255; tertile 2 = 54 μg/d (43–65 μg/d), n = 255; and tertile 3 = 90 μg/d (66–386 μg/d), n = 256. Values are adjusted means ± SEMs. Means were adjusted for age, sex, race, Tanner stage, systolic blood pressure, fat-free soft tissue mass, fat mass, socioeconomic status, moderate and vigorous physical activity, and dietary intakes of total energy, fiber, calcium, vitamin C, vitamin D, and sodium. Labeled means without a common lowercase letter differ, P < 0.05.
