Was It the Nephrologists or the Fluid? John W. Pickering, PhD, Azrina Md Ralib, MBChB, Zoltán H. Endre, MBBS, PhD, FRACP  American Journal of Kidney Diseases  Volume 58, Issue 1, (July 2011) DOI: 10.1053/j.ajkd.2011.04.012 Copyright © 2011 National Kidney Foundation, Inc. Terms and Conditions

Figure 1 Schematic of 3 scenarios for (A) creatinine level and (B) glomerular filtration rate (GFR) changes in a 70-kg man whose GFR decreases by 50% at time 0. Compared with the no-intervention scenario (solid lines), intervention with fluids that dilute creatinine decreases creatinine level (dotted line in A), but does not improve GFR. An intervention causing a gradual improvement in GFR (dashed line in B) also decreases creatinine level (dashed line in A).
