Figure 1. Difference between measured and estimated versus estimated GFR.
All panels show the difference between measured and estimated versus estimated GFR. A smoothed regression line is shown with the 95% CI (computed by
using the lowest smoothing function in R), using quantile regression, excluding the lowest and highest 2.5% of estimated GFR.
CG: Cockcroft-Gault equation; CGI: Cockcroft-Gault equation (calculated with ideal weight); CKD-EPI: the Chronic Kidney Disease Epidemiology Collaboration
equation; CrCl: Creatinine clearance; MCQ: Mayo Clinic Quadratic Equation; sMDRD: simplified MDRD study equation.
