FIG. 1.

Correlation matrix of relative abundance of plasma proteins associated with vitamin K status. Plasma proteins were associated with plasma protein induced vitamin K absence-II (PIVKA-II) concentration or differentially abundant by vitamin K status (PIVKA-II> or ≤2 μg/L), passing a relaxed discovery threshold, q < 0.20 (n = 27). Blue and red colors depict positive and negative correlation coefficients, respectively, and darker colors represent stronger correlation. Correlation coefficients less than ±0.01 were denoted as 0.
