Estimation of the Age-Dependent Decline of Glomerular Filtration Rate from Formulas Based on Creatinine and Cystatin C in the General Elderly Population.
Background/Aims: To evaluate the performance of estimation formulas for glomerular filtration rate (GFR) based on creatinine and cystatin C in elderly. Methods: This study includes 2,931 men and women comprising nine age cohorts (60-93 years) from a longitudinal population-based project in Sweden. The participants were divided into four age groups. GFR was estimated from four formulas: the Modific
