Fig. 2From: Different equations for estimating age-related changes of glomerular filtration rate in the healthy populationTrend of eGFR by CKD-EPI, FAS, and Xiangya equations with aging in healthy population. eGFR level was presented as mean and 95% confidence interval in each age-group. eGFR: estimated glomerular filtration rate. CKD-EPI: chronic kidney disease epidemiology collaboration equation based on serum creatinine; FAS: full age spectrum based on serum creatinine and ageBack to article page
