Erratum Regarding “Cystatin C in Prediction of Acute Kidney Injury: A Systematic Review and Meta-analysis” (Am J Kidney Dis 2011; 58:356-365)    American Journal of Kidney Diseases  Volume 59, Issue 4, Pages 590-592 (April 2012) DOI: 10.1053/j.ajkd.2012.01.002 Copyright © 2012 National Kidney Foundation, Inc.

Figure 2 Summary receiver operating characteristic (SROC) plot of serum cystatin C level to predict acute kidney injury across all settings. Based on combined sensitivity and specificity weighted for sample size of each study reflected by the size of the circles, showing average sensitivity and specificity estimate of the study results (open diamond) and 95% confidence region around it. The 95% prediction region represents the confidence region for a forecast of the true sensitivity and specificity in a future study. Heterogeneity is great, represented by the I2 of 94%.

Figure 3 Summary receiver operating characteristic (SROC) plot of early (<24 hours) serum cystatin C level to predict acute kidney injury. Based on combined sensitivity and specificity weighted for sample size of each study reflected by the size of the circles, showing average sensitivity and specificity estimate of the study results (solid square) and 95% confidence region around it. The 95% prediction region represents the confidence region for a forecast of the true sensitivity and specificity in a future study. The heterogeneity is great, represented by the I2 of 92%.

Figure 4 Summary receiver operating characteristic (SROC) plot of urinary cystatin C excretion to predict acute kidney injury. Based on combined sensitivity and specificity weighted for sample size of each study reflected by the size of the circles, showing average sensitivity and specificity estimate of the study results (solid square) and 95% confidence region around it. The 95% prediction region represents the confidence region for a forecast of the true sensitivity and specificity in a future study. The heterogeneity is great, represented by the I2 of 98%.
