FIGURE 3:

Net reclassification of AKI from KDIGO to the Delta-Creatinine-based staging system. The percentages of each KDIGO stage reclassified upwards (rightwards) to higher or downwards (leftwards) to the lower Delta-Creatinine stage are shown in the figure. For example, for KDIGO Stage 1 AKI, while most would be reclassified as Delta-Creatinine Stage 1, 7.5% would be reclassified to the lower Delta-Creatinine Stage 0, and 13.8% would be reclassified to the higher Delta-Creatinine Stage 2. NRI 9.5% (95% CI 6.0–13.0%). Figure adapted from the CKD Prognosis Consortium (http://www.jhsph.edu/ckdpc).
