WebResults: In general, creatinine-based equations resulted in lower eGFR-estimation and in higher necessity of drug dose adjustment than cystatin C-based equations. Concordance was high between creatinine-based equations alone (ICCs 0.87) and between cystatin C-based equations alone (ICCs 0.90 to 0.96), and moderate between creatinine-based WebCystatin C is a more reliable biomarker for estimating eGFR since it is not subject to muscle conditions. 19 Furthermore, cystatin C is reportedly a more sensitive serum marker in detecting early renal injury than creatinine. 20 However, a few population-based studies have focused on the association between eGFR based on cystatin C and muscle ...
