Diverse Associations of Plasma Selenium Concentrations and SELENOP Gene Polymorphism with Metabolic Syndrome and Its Components

Figure 1

Representation of restricted cubic spline logistic regression models for ln-transformed selenium and risk of MetS and its components. The solid lines represent adjusted odds ratios of (a) MetS, (b) central obesity, (c) hypertriglyceridemia, (d) low HDL-C, (e) high blood pressure, and (f) hyperglycemia based on restricted cubic splines for ln-transformed selenium with 5 knots at the 10th, 25th, 50th, 75th, and 90th percentiles of its distribution. And dashed lines surrounding the solid lines represent the 95% confidence intervals. Confounding factors including sex, age (years), and body mass index (kg/m²), smoking (current, former, and never), drinking (current, former, and never), vigorous activity (yes or no), and education level (none or elementary school, middle school, and high school or college) were adjusted. OR: odds ratio; MetS: metabolic syndrome.
