Ordinary linear/logistic regression and instrumental variable regression of the association between serum 25-OH-D and cardiovascular risk factors.

¤2SLS analyses of the association between vitamin D status and cardiovascular risk factors using filaggrin genotype as instrument for vitamin D status.
&Both OLS and IV models were adjusted for study population, age, gender, education, season, intake of fish, physical activity, smoking habits, alcohol consumption, and body mass index. Participants with self-reported use of lipid lowering medication were excluded (n = 396).
£Both OLS and IV models were adjusted for study population, age, gender, education, season, intake of fish, physical activity, smoking habits, alcohol consumption, and body mass index. Participants with self-reported use of blood pressure lowering medication were excluded (n = 1,138).
$Both OLS and IV models were adjusted for study population, age, gender, education, season, intake of fish, physical activity, smoking habits, and alcohol consumption.
Abbreviations: CI, confidence interval; 25-OH-D, 25-hydroxyvitamin D; OR, odds ratio.

以丝聚蛋白（filaggrin）基因型作为维生素D状态的工具变量，开展维生素D状态与心血管危险因素间关联的两阶段最小二乘（2SLS）分析。
普通最小二乘（OLS）与工具变量（IV）模型均针对研究人群、年龄、性别、受教育程度、检测季节、鱼类摄入量、体力活动、吸烟习惯、饮酒情况及体质量指数进行了混杂校正。本研究排除了自我报告服用调脂药物的参与者（n=396）。
