Association between dietary vitamin K intake and lipid metabolism among populations with cardiovascular disease.

ABSTRACT:

Background

The objective of this investigation was to examine the correlation between intake of dietary vitamin K and lipid metabolism in cardiovascular disease populations.

Methods

The data for this investigation were obtained from the National Health and Nutrition Examination Survey (NHANES) 2003-2014. The exposure variable was the total daily intake of dietary vitamin K (μg). Triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) comprised the lipid indicators. To investigate the relationship between vitamin K intake and lipid metabolism, the following analyses were conducted: weighted multiple linear regression, smoothing curve fitting, generalized additive models, threshold analysis, subg
