Correlations are shown with the coefficient r or 95% Cl of the mean difference between the patients with complications and without.

Cre/CysC, creatinine to cystatin C ratio; CV, cardiovascular; DN, diabetic nephropathy; DPN, diabetic peripheral neuropathy; DR, diabetic retinopathy; LEAD, lower-extremity arterial disease.
