Cystatin C (Cys C) versus creatinine (Cr) as markers of glomerular filtration rate (GFR). (A) Scatterplot of correlation coefficients (r) for 1/Cys C and 1/Cr with measured GFR. Horizontal line represents the cumulative mean r of all studies analyzed. (B) Scatterplot of receiver operating characteristic plot area under the curve (AUC) values for Cys C and Cr. Horizontal line represents the cumulative mean of all 14 data sets.
