The correlation (or loading) between each covariate and the cluster components.

The loadings produced in a VARCLUS analysis are analogous to factor loadings in a factor analysis. Each loading represents the correlation of the variable with the cluster component. The loadings of the variables assigned to the cluster component are highlighted in bold. Abbreviation: Fasting insulin (Ins), postchallenge insulin (PCIns), fasting glucose (Glu), postchallenge glucose (PCGlu), body mass index (BMI), waist/hip ratio (WHR), high density lipoprotein cholesterol (HDL), triglycerides (Trig), systolic blood pressure (SBP), diastolic blood pressure (DBP).
