¹Unadjusted analyses are based on 1-way ANOVA. Adjusted analyses are based on analysis of covariance, adjusted for age, vitamin K intake, smoking, and triglycerides. When the main effect was significant, individual tertiles were compared using Tukey's HSD.

²Data are means ± SE. Within gender, means in a row with superscripts without a common letter differ, P < 0.05.

³Data are least-square means ± SE, adjusted for age, vitamin K intake, smoking, and triglycerides. Within gender, means in a row with superscripts without a common letter differ, P < 0.05.
