Each correlation coefficient is adjusted for the other biomarkers except for MFFM. Correlations between MFFM and other variables are not adjusted for Ins and Trig, except for the correlations between MFFM and Ins and Trig.

UA, uric acid; eGFR, estimated Glomerular filtration rate; Ins, fasting insulin; Trig, fasting triglycerides; MFFM, glucose disposal rate (M) corrected for fat free mass (FFM); Hcy, Homocysteine; sICAM, soluble intercellular adhesion molecule-1.
