  1. eGFR, estimated glomerular filtration rate
  2. a)By CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) equation; b)eGFR < 60 mL/min/1.73m2, a follow-up interval of 3 to 6 months is recommended; c)Useful for evaluating renal function in younger men with high muscle mass or older women with low muscle mass
