Factors Other than GFR Affecting Serum Cystatin C Levels (2008, neutral): “equations to estimate GFR from serum creatinine.(4) The association with race varies by modeling strategy and weakened by adjustment for measurement error in GFR in this paper compared to the GFR-estimating equation.”
A New Equation to Estimate Glomerular Filtration Rate (2009, background): “Mean age (SD), y 47 (15) 47 (15) 50 (15) 0.001 Age, n (%) 0.001 40 y 2058 (37) 1018 (37) 1136 (29) 41–65 y 2751 (50) 1403 ( 51 ) 2192 (56) 65 y 695 (13) 329 (12) 568 (15) 66–70 y 476 (9) 220 (8) 254 (7) 71–75 y 150 (3) 66 (2) 185 (5) 76–80 y 41 (0) 30 (1) 92 (2) 80 y 28 (0) 13 (0) 37 (0)”
Two Novel Equations to Estimate Kidney Function in Persons Aged 70 Years or Older (2012, methodology): “Elderly persons have generally been underrepresented—even in large cross-sectional data sets of equation development for GFR (12, 13, 17, 18)—and the need for an ageadapted equation has been stated repeatedly (19-22).”
Serum indoxyl sulfate is associated with vascular disease and mortality in chronic kidney disease patients. (2009, methodology): “To describe the true GFR as closely as possible, the estimated GFR combining Scr and CysC measurements (CKD-epi) was calculated for all nondialyzed patients according to the following recently published (14) “CKD-epi” equation: 177.”
