Specifically, we could demonstrate an inverse association with renal function as displayed by highly significant correlations with the glomerular filtration rate of cystatin C (r = -0.649, P < 0.001), cystatin C (r = 0.638, P < 0.001), creatinine (r = 0.352, P < 0.0001) and urea (r = 0.400, P < 0.001) serum concentrations (Table 3 ), indicating renal clearance of suPAR.
