Distribution according to body mass index (BMI) (kg/m2) and age of three levels of glomerular filtration rate (GFR) (mL/min) estimated with both Cockcroft–Gault equation and creatinine clearance calculated using 24-hour urine collection in a population of men aged 65 and older with normal serum creatinine values. No men aged 85 and older with a BMI of 30.0 and higher had complete data for serum creatinine, BMI, and calculated creatinine clearance.
