  1. aThe correlation coefficients shown are controlled for traditional risk factors (age; sex; race; smoking, alcohol and exercising status; diabetes; waist; systolic blood pressure; total cholesterol; high-density lipoprotein cholesterol; triglycerides) in multivariable regression models. ELAM, endothelial leukocyte adhesion molecule; GFR, glomerular filtration rate; ICAM, intercellular adhesion molecule; IL, interleukin; VCAM, vascular adhesion molecule.
