"BACKGROUND: Equations to estimate glomerular filtration
rate (GFR) are routinely used to assess kidney function. Current
equations have limited precision and systematically underestimate
measured GFR at higher values." 1
"CONCLUSION: The CKD-EPI creatinine equation is more accurate than
the Modification of Diet in Renal Disease Study equation and could
replace it for routine clinical use." 13
