Figure 2 Graphic representation of the relationship between body mass index (BMI), steady-state plasma glucose, and coronary heart disk risk factors for regression model B. Dependent variables: coronary heart disease risk factors (age, systolic blood pressure, diastolic blood pressure, total cholesterol, triglycerides, high-density lipoprotein [HDL] cholesterol, low-density lipoprotein [LDL] cholesterol, glucose response, and insulin response). Independent variables: BMI, steady-state plasma glucose, and the interaction term. R_B = multiple correlation coefficient for the analyses based on regression model B.
